Medical Use of Radioisotopes Medical Imaging Thanks to radioactive isotopes, images can be obtained via gamma camera or a PET scan in nuclear diagnostics. Radioisotopes are used to follow the paths of biochemical reactions or to determine how a substance is distributed within an organism. Another important use is to predict the effects of surgery and assess changes since treatment. Bi-213 has a 46-minute half-life. This is prepared from ytterbium-176 which is irradiated to become Yb-177 (which decays rapidly to Lu-177). * LEU is dissolved in acid then brought to criticality in a 200-litre vessel. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Production and Clinical Applications of Radiopharmaceuticals and Medical Radioisotopes in Iran Semin Nucl Med . Rubidium-82 (1.26 min): At Lansing in Michigan, Niowave is using a superconducting electron linear accelerator to produce isotopes from fission of low-enriched uranium. Rhenium-186 is a newer product for this. Chapter 53; Applications of Radio-isotopes in Medicine n 595. bone etc. Caesium-131 (9.7 d):  Iron-59 (46 d): These are positron emitters used in PET for studying brain physiology and pathology, in particular for localising epileptic focus, and in dementia, psychiatry, and neuropharmacology studies. Iodine-131 (8 d)*: Its distribution can be tracked according to the radiation it gives off. 50%) above demand, due to decay of Mo-99 in transit, despite the six-day TBq/Ci quantification. HFR at Petten in Netherlands (supplied via IRE and Curium). A licence application was submitted to the NRC in March 2017, with a view to meeting half of US demand for Mo-99. HEU use needs to be minimised, though conversion to LEU targets will reduce capacity. Radium was the first isotope used for cancer treatment at the beginning of the 20th … Growth of Nuclear Medicine in India – (DRDO) Publications. The decay product (often gamma emission) can be located and the intensity measured. Radioisotopes in Medicine. Lung function tests routinely made using xenon-133 (133 Xe) are particularly useful in diagnosis of malfunctions of lung ventilation. Radioactive chemical tracers emitting gamma rays or positrons can provide diagnostic information about internal anatomy and the functioning of specific organs, including the human brain. Used as industrial tracers. Gamma camera can accurately detect disease progression and staging in vital organs. for prostate cancer. They are used to measure engine wear, analyze the geological formation around oil wells, and much more. The patient is then irradiated with thermal neutrons or protons which are strongly absorbed by the boron, producing high-energy alpha particles which kill the cancer. Used for brachytherapy, emits soft x-rays. Output will replace that from NRU at Chalk River in Canada. Erbium-169 (9.4 d): Gamma imaging by either method described provides a view of the position and concentration of the radioisotope within the body. Medical Applications Nuclear Medicine. Iodine-124 (4.2 d): Further grants from NNSA have totalled $25 million under a $50 million cooperative agreement for Mo-99 production without use of HEU. Both SAFARI-1 and NTP Radioisotopes have implemented operational restrictions to curb the spread of COVID-19 on-site. They are used to measure engine wear, analyze the geological formation around oil wells, and much more. Lu-177 and Y-90 are becoming the main RNT agents. It reviewed the Mo-99 supply chain to identify the key areas of vulnerability, the issues that need to be addressed, and the mechanisms that could be used to help resolve them. Positioning of the radiation source within (rather than external to) the body is the fundamental difference between nuclear medicine imaging and other imaging techniques such as X-rays. Tenders for this closed in June 2010, but evidently no immediate progress was made. Very effective in reducing the pain of prostate and bone cancer. Thorium-227 (18.7 d): Jalilian AR(1), Beiki D(2), Hassanzadeh-Rad A(2), Eftekhari A(3), Geramifar P(2), Eftekhari M(4). Also used to image the thyroid using PET. Fluorine-18 (110 min) as FLT (fluorothymidine), F-miso (fluoromisonidazole), 18F-choline: Supply capacity is always substantially (e.g. In September 2010 JSC Isotope signed a framework agreement with MDS Nordion to explore commercial opportunities outside Russia on the basis of this Isotop-NIIAR JV, initially over ten years. Radioisotopes have revolutionized medical practice, where they are used extensively. Some iodine-131 is produced at Leningrad nuclear power plant from tellurium oxide, using irradiation channels in the RBMK reactors. However, their application in some other fields have not been fully realized. Radionuclide therapy has progressively become more successful in treating persistent disease and doing so with low toxic side-effects. In 2015, NorthStar Medical Radioisotopes signed an agreement with Westinghouse to investigate production of Mo-99 in nuclear power reactors using its Incore Instrumentation System. Another radionuclide recovered from Th-232, but by natural decay via thorium-228, is Pb-212, with a half-life of 10.6 hours. Radioisotopes typically have short half-lives and typically decay before their emitted radioactivity can cause damage to the patient’s body. On the other hand, we have unleashed the awesome … Used especially for melanoma, breast cancer and ovarian cancer. The global radioisotope market was valued at $9.6 billion in 2016, with medical radioisotopes accounting for about 80% of this, and it is poised to reach about $17 billion by 2021. Radioactive tracers are also used in many medical applications, including both diagnosis and treatment. The radioisotope circulates through the body or is taken up only by certain tissues. New procedures combine PET with computed X-ray tomography (CT) scans to give co-registration of the two images (PET-CT), enabling 30% better diagnosis than with a traditional gamma camera alone. Generally neutron-rich ones and those resulting from nuclear fission need to be made in reactors; neutron-depleted ones are made in cyclotrons. For some years, three-quarters of the Mo-99 was made in three reactors: NRU in Canada (30-40%), HFR in Netherlands (30%) and BR-2 in Belgium (10%). Applications of Radioisotopes. Therapeutic applications of radioisotopes typically are intended to destroy the targeted cells. Radium-223 (11.4 d):  In the USA there are over 20 million nuclear medicine procedures per year, and in Europe about 10 million. Radioactive isotopes have many useful applications. In February 2018, Rosatom stated that the Mo-99 produced from the plant in 2017 will be enough for 5000 medical procedures. Gamma camera can accurately detect disease progression and staging in vital organs. Beta emitter. All were awarded cooperative agreements of $15 million each by August 2019 for Mo-99 production, which the NNSA said should total about 110 six-day TBq per week. Pb-212 has a half-life of 10.6 hours, and beta decays to Bi-212 (1 hour half-life), then most beta decays to Po-212. In Canada the government has an Isotope Technology Acceleration Program (ITAP) to promote R&D on non-reactor based isotope production, particularly through the Medical Isotope Program (MIP). In some cases radioisotopes are used in. Radioisotopes are very widely used in medicine, in particular for diagnostic tests. STUDY. Produced from Mo-99 in a generator. Treatment may involve significant radioactivity (e.g. Rosenergoatom in Russia is implementing plans to increase its global market share of Co-60 from 15% to 30%, mainly from Kursk. A new and still experimental procedure uses boron-10, which concentrates in the tumour. However, the main radioisotopes such as Tc-99m cannot effectively be produced without reactors.*. To treat an overactive thyroid gland and certain kinds of thyroid cancer by using sodium iodide labelled with radioactive iodine. Sodium-24 (15 h): At Russia's Kurchatov Institute the 20 kW ARGUS Aqueous Homogeneous Reactor (AHR) has operated since 1981, and R&D on producing Mo-99 from it is ongoing. I-131 is used to treat the thyroid for cancers and other abnormal conditions such as hyperthyroidism (over-active thyroid). After about four to six hours, the exposure rate of the patient has fallen to less than 25 microsieverts per hour at one metre and the patients can be discharged from hospital. •Environment Studies and Agriculture •Medicine •Industry 4. The Ac-225 (half-life 10 days) is formed from radioactive decay of radium-225, the decay product of long-lived thorium-229, which is obtained from decay of uranium-233, which in turn is formed from thorium-232 by neutron capture in a nuclear reactor. In nuclear medicine, radioisotopes are used for diagnosis, treatment, and research. A third method is by proton bombardment of Mo-100 in an accelerator of some kind. Canada Light Source (CLS) in Saskatoon is using a linear accelerator to bombard Mo-100 targets with x-rays, and has produced some Mo-99 for MIP. A 132-hour test run of Phoenix's high-flux neutron generator was in June 2019. In September 2008 the World Council on Isotopes was set up, based in South Korea, to promote isotope technologies. Radioisotopes of gold and ruthenium are also used in brachytherapy. Here are the two main uses of radioisotopes in the industry today. They are used to measure engine wear, analyze the geological formation around oil wells, and much more. This is done in power reactors, usually RBMK or Candu. Used in to image the skeleton and heart muscle in particular, but also for brain, thyroid, lungs (perfusion and ventilation), liver, spleen, kidney (structure and filtration rate), gall bladder, bone marrow, salivary and lacrimal glands, heart blood pool, infection, and numerous specialised medical studies. In nuclear medicine, tracer radioisotopes may be taken orally or be injected or inhaled into the body. Used in studies of iron metabolism in the spleen. This is still about two days from the end of irradiation, so some 167,000 TBq/yr must be made in the actual reactors to allow for cooling, processing and decay en route to the users. Phase 1 of the Mo-99 production complex with capacity of 1700 TBq/yr was commissioned in December 2010, and Phase 2 was commissioned in June 2012 taking total capacity to 1480 TBq/yr (evidently 6-day activity). It has a half-life of six hours which is long enough to examine metabolic processes yet short enough to minimize the radiation dose to the patient. In certain cases radiation can be used to treat diseased organs or tumours.Medical radioisotopes are made from materials bombarded by neutrons in a reactor, or by protons in an … The supply chain’s economic structure therefore had to be changed to attract additional investment in production capacity as well as the necessary reserve capacity, and all supply chain participants worldwide need to agree on and implement the required changes. Used for TAT especially prostate cancers. Lu-177 is essentially a low-energy beta-emitter (with some gamma) and the carrier attaches to the surface of the tumour. Radioisotopes in Medicine Radiotherapy can be used to treat some medical conditions, especially cancer. Used as the 'parent' in a generator to produce technetium-99m. Chromium-51 (28 d): To detect position of blood clots or thrombosis using Sodium-24 injected in the bloodstream. Registered office: Tower House, 10 Southampton Street, London, WC2E 7HA, United Kingdom, Reuse of World Nuclear Association Content, subsidiary of NorthStar Medical Technologies, A Supply & Demand Update of the Mo-99 Market, Feasibility of Producing Molybdenum-99 on a Small Scale Using Fission of Low Enriched Uranium or Neutron Activation of Natural Molybdenum, Nuclear Energy and Sustainable Development. Therapy Radioisotopes prove to be useful in the application of brachytherapy, the procedure for using temporary The application of radioisotopes in tracing, radiography, food preservation and sterilization, eradication of insects and pests, medical diagnosis and therapy, and new variety of crops in agricultural field is briefly described. The bismuth is obtained by elution from an Ac-225/Bi-213 generator similar to the Mo-99/Tc-99 one. Smaller gamma irradiators, often utilising Cs-137, having a longer half-life, are used for treating blood for transfusions and for other medical applications. (MURR started supplying iodine-131 in November 2018 after a three decade US hiatus.). the treatment of neoplasms in these organs. Sterilisation by radiation has several benefits. The nuclear technique by using radioactive isotopes in the nuclear medicine field began in the 1930s as a manifestation of the development of science and technology. A comprehensive review has been made to discuss the role of various radionuclides of lanthanide series elements in the field of nuclear medicine. This is boron neutron capture therapy. 4. Large-scale irradiation facilities for gamma sterilisation are installed in many countries. The targets are then processed to separate the Mo-99 and also to recover I-131. changes in the movement, distribution and concentration in the molecule can be detected by … Radioisotopes have found extensive use in diagnosis and therapy, and this has given rise to a rapidly growing field called nuclear medicine. Cobalt-60 (5.27 yr): Historically reactor irradiation prices have been too low to attract new investment, and full cost recovery is needed to encourage new infrastructure. Radiopharmacology is radiochemistry applied to medicine and thus the pharmacology of radiopharmaceuticals (medicinal radiocompounds, that is, pharmaceutical drugs that are radioactive).Radiopharmaceuticals are used in the field of nuclear medicine as radioactive tracers in medical imaging and in therapy for many diseases (for example, brachytherapy). This new medical isotope supply is to be produced using General Atomics’ innovative Selective Gaseous Extraction (SGE) technology to extract the molybdenum from the targets. Northwest Medical Isotopes (NWMI) planned to produce half of North America’s demand for Mo-99 from 2017, using LEU targets. Radioisotopes have large number of applications in different fields like medicine, engineering, biology, chemistry, archeology, agriculture and industry. Medical Applications. It is safer and cheaper because it can be done after the item is packaged. In 2017 Rosatom announced the establishment of a radiopharmaceutical production plant at the Institute of Reactor Materials (IRM), which had started with lutetium-177, producing 24 TBq of it in 2016 (650 Ci). 3. Terms in this set (33) principle of radiotracer applications. Cancerous growths are sensitive to damage by radiation. One of the main properties of radioisotopes is that you can easily detect … In developed countries (a quarter of the world population) about one person in 50 uses diagnostic nuclear medicine each year, and the frequency of therapy with radioisotopes is about one-tenth of this. Xenon-133 (5 d)*: However, NRU ceased production in October 2016, and the other two have limited remaining service life. * Some Tc-99m is produced in accelerators but it is of lower quality and at higher cost. Lung function tests routinely made using xenon-133 (133 Xe) are particularly useful in diagnosis of malfunctions of lung ventilation. Used for diagnosis of coronary artery disease other heart conditions such as heart muscle death and for location of low-grade lymphomas. Rhenium-188 (17 h): Lutetium-177 dotatate or octreotate is used to treat tumours such as neuroendocrine ones, and is effective where other treatments fail. Its half-life is long enough to allow sophisticated preparation for use. The radioisotope that generates the radiation can be localised in the required organ in the same way it is used for diagnosis – through a radioactive element following its usual biological path, or through the element being attached to a suitable biological compound. Yttrium-90 (64 h)*: i. RBCs can be tagged with 51 Cr. Gravity. Some radioisotopes commonly-used in industry and science can be found in the tables below. Title: Application of Radioisotopes in Diagnosis and Treatment of Diseases: Presenter: John Pemba Radiopharmacist Nuclear Medicine Unit BMC 1 Application of Radioisotopes in Diagnosis and Treatment of DiseasesPresenter John Pemba Radiopharmacist Nuclear Medicine UnitBMC 2 Presentation outline Transport regulation and denial of shipment impede reliable supply. The radioisotope then circulates through the body or is taken up only by certain tissues. Areva and Bruce Power are aiming to produce Mo-99 among other isotopes in the latter’s Candu power reactors – see below. Once a radioactive form of one of these substances enters the body, it is incorporated into the normal biological processes and excreted in the usual ways. It is an isotope of the artificially-produced element technetium and it has almost ideal characteristics for a nuclear medicine scan, such as with SPECT. A more recent development is positron emission tomography (PET) which is a more precise and sophisticated technique using isotopes produced in a cyclotron. Use Of Radioisotopes In Medicine Definition Radioisotopes are chemical elements that are formed when atoms undergo natural decay. This approach forms the basis of radiotherapy, which is commonly used to treat cancer and other conditions involving abnormal tissue growth, such as hyperthyroidism. Longer-term NorthStar is considering a non-reactor approach – see below. The doses per therapeutic procedure are typically 20-60 Gy. Yttrium-90 is used for treatment of cancer, particularly non-Hodgkin's lymphoma and liver cancer, and it is being used more widely, including for arthritis treatment. * A single production facility could have four such reactors. Used to make brachytherapy permanent implant seeds for early stage prostate cancer. In 2014 another plan using the US University Reactor Network was announced. For PET imaging, the main radiopharmaceutical is fluoro-deoxy glucose (FDG) incorporating F-18 – with a half-life of just under two hours – as a tracer. Samarium-153 (47 h): After administering the correct dose, the implant wire is removed to shielded storage. A need for increased production capacity and more reliable distribution is evident. In addition to imaging, radionuclide therapy can be used to treat conditions such as hyperthyroidism, thyroid cancer, and blood disorders. Holmium-166 (26 h): (Ed.) In June 2018 it was announced that Ontario Power Generation's Darlington plant will begin production of Mo-99 by the end of 2019. Used as a marker to estimate organ size and for in-vitro diagnostic kits. NRU at Chalk River in Canada (supplied via MDS Nordion) ceased production in October 2016, and the reactor closed down in March 2018. Clinical trials for leukaemia, cystic glioma, and melanoma are underway. These documents were forerunners to publication of codes on teletherapy, brachytherapy and nuclear medicine. It decays with positron emission, so used as tracer with PET, for imaging malignant tumours. With any therapeutic procedure the aim is to confine the radiation to well-defined target volumes of the patient. In January 2009 Babcock & Wilcox (B&W) announced an agreement with international isotope supplier Covidien to produce Mo-99 sufficient for half of US demand, if a new process was successful. The uses of radioisotopes in therapy are comparatively few, but nevertheless important. A Th-229/Ac-225 generator is eluted about eight times per year at ORNL, but output is limited. Radioisotope: Treatment : I-131: thyroid disease: Tc-99m: gastrointestinal bleed: Th-201: coronary artery: Co-60: Chemotherapy: C-11, O-15, N-13, F-13: positron emission tomography: Ir-192, I-125: internal medicine … brain studies, infection and colon transit studies. Also it called for proposals for an LEU-based supply of Mo-99 for the US market, reaching 111 six-day TBq per week by mid-2013, a quarter of world demand. Used for specialist diagnostic studies, e.g. Formerly this radioisotope was made in Canada’s NRU at Chalk River until it closed but Bruce B nuclear power plant has increased its output for Co-60. Radioisotopes is a naturally or artificially produced radioactive isotope of an element. An experimental development of this is Neutron Capture Enhanced Particle Therapy (NCEPT) which involves injecting a patient with a neutron capture agent shortly before irradiation with protons or heavy ions. There are about 40 activation product radioisotopes and five fission product ones made in reactors. Krypton-81m (13 sec) from rubidium-81 (4.6 h): Palladium-103 (17 d): Medical radioisotopes are classified as essential products and, as such, research reactor SAFARI-1 and South African manufacturer NTP Radioisotopes continue operations to produce them. It reports production of Mo-99, I-131, Sr-89 and Xe-133 among many others. Gamma emission imaging has been successfully applied to almost every organ of the b … Application of radioisotopes in inflammation Curr Med Chem. earliest application of radioisotopes was in the 1950s, 131 I for the diagnosis and treatment of thyroid disease. Derived from germanium-68 in a generator. To be used as tracers in the effectiveness of fertilisers using nitrogen-15 and phosphorus -32. Safari in South Africa (supplied from NTP). Understand how radioisotopes are used in medical science Assess how radioisotopes are used in environmental and earth sciences Recognize how the application of radioisotopes … In mid-2013 Los Alamos National Laboratory announced that it had recovered Mo-99 from low-enriched sulphate reactor fuel in solution, raising the prospect of this process becoming associated with commercial reprocessing plants as at La Hague in France. Radioisotopes: Applications in Bio-Medical Science Singh N. Considerable medical research is being conducted worldwide into the use of radionuclides attached to highly specific biological chemicals such as immunoglobulin molecules (monoclonal antibodies). For diagnosis, these radioactive substances are administered in the body of the patient. Write. These cells. The report identifies possible changes needed. As indicated above, most of the world's supply of Mo-99 for this comes from only five reactors, all of them 49 to 58 years old (in mid-2016). Increasingly used for diagnosis of thyroid function, it is a gamma emitter without the beta radiation of I-131. This book contains two sections: Radioisotopes … Pure beta emitter and of growing significance in therapy, especially liver cancer. LVR-15 at Rez in Czech Republic (supplied via IRE). BR-2 at Mol in Belgium (supplied via IRE and Curium). Kr-81m gas can yield functional images of pulmonary ventilation, e.g. A contract with the Karpov Institute of Physical Chemistry provides for delivery of 2.6-3.0 TBq of I-131 per week. Radioisotopes that emit γ-rays are particularly useful because they have the advantage of ... Radionuclides for medical use are produced in nuclear reactors and particle accelerators. In addition, several sources of supply had ramped up production to lift the baseline supply capacity for the 2017 and 2018 periods to a level safely above the revised market demand. A radioisotope used for diagnosis must emit gamma rays of sufficient energy to escape from the body and it must have a half-life short enough for it to decay away soon after imaging is completed. Author information: (1)Nuclear Science and Technology Research Institute, Tehran, Iran. Radioactive isotopes, or radioisotopes, are species of chemical elements that are produced through the natural decay of atoms. 2006;13(8):959-65. World demand for Mo-99 was 23,000 six-day TBq/yr* in 2012, but has apparently dropped back to about 18,500 since. A second production facility is Karpov IPC. 2016 Jul;46(4):340-58. doi: 10.1053/j.semnuclmed.2016.01.006. * 23,000 TBq is on the basis of activity at 6 days from production reference point, i.e. Carbon-11, Nitrogen-13, Oxygen-15, Fluorine-18: They are used to measure engine wear, analyze the geological formation around oil wells, and much more. High-specific-activity (HSA) Co-60 is used for brain cancer treatment. Bismuth-213 (half-life: 46 min): The radioisotopes have numerous applications in medicine, agriculture, industry and pure research. Scandium-47 (4.5 d) Kara Rogers is the senior editor of biomedical sciences at Encyclopædia Britannica, where she oversees a range of content from medicine and genetics to microorganisms. The disposable syringe is an example of a product sterilised by gamma rays. Used in TAT for cancers or alpha radioimmunotherapy, with decay products Bi-212 (1 h) and Po-212 delivering the alpha particles. Rhenium-186 (3.8 d): Strontium-82 (25 d): 1. North America is the dominant market for diagnostic radioisotopes with close to half of the market share, while Europe accounts for about 20%. As radioisotopes are identical chemically with stable isotopes of the same element, they can … Besides their use in the industry sector, radioisotopes are also transforming nuclear medicine and the food preservation and sterilization industry. P-32 is used to control this excess. Here are some common radioisotopes that are used to treat diseases. In recent years specialists have also come from radiology, as dual PET/CT (positron emission tomography with computerised tomography) procedures have become established, increasing the role of accelerators in radioisotope production. Osiris was due to shut down in 2015 but apparently continued to at least 2016. Being developed for diagnosis and treatment of liver tumours. Formerly used for external beam radiotherapy, now almost universally used for sterilising. The process will use Areva NP's patent-pending method of producing radioisotopes using a heavy water nuclear power plant. The FDG is readily incorporated into the cell without being broken down, and is a good indicator of cell metabolism. Although radiotherapy is less common than diagnostic use of radioactive material in medicine, it is nevertheless widespread, important, and growing. Since 2009, (131)I-meta-iodobenzylguanidine has been locally available for diagnostic applications. Radioisotopes in Water Resources & the Environment Spell. Used to beta irradiate coronary arteries from an angioplasty balloon. About 40% of it is supplied by MDS Nordion, 25% from Mallinckrodt (formerly Covidien), 17% from IRE, and 10% from NTP. Earlier reports quoted 4800 TBq/yr, and Rosatom aimed for 20% of the world Mo-99 market by 2014, supplied internationally through Nordion. The eventual tagging of these cells with a therapeutic dose of radiation may lead to the regression – or even cure – of some diseases. Exposure to radiation generally is considered harmful to the human body, but radioisotopes are highly valuable in medicine, particularly in the diagnosis and treatment of disease. The isotopes can be administered by injection, inhalation, or orally. Artificial radioisotopes are produced from stable elements that are bombarded with neutrons. — 330 p. — ISBN: 9533077482 9789533077482The subject matter will by highly useful to the medical and paramedical staff in hospitals, as well as researchers and scholars in the field of nuclear medicine medical physics and nuclear bio-chemistry etc. In the case of x-rays the source is on the outside … TAT using lead-212 is increasingly important for treating pancreatic, ovarian, and melanoma cancers. Teletherapy is effective in the ablation of tumours rather than their removal; it is not finely tuned. Radioisotopes are used to follow the paths of biochemical reactions or to determine how a substance is distributed within an organism. Naturally-occurring radioisotopes in industry and science Radioisotope Half-life Use; Hydrogen-3 (tritium) 12.32 years: Used to … In 2017, production was: HFR in the Netherlands (40%), BR-2 in Belgium (20%), Maria in Poland (5%), Safari-1 in South Africa (15%), Opal in Australia (15% increasing to 24% from mid-2018) and LWR-15 in the Czech Republic (5%). It is produced by irradiating calcium-46 to produce Ca-47 which decays to Sc-47. Strong beta emitter for high dose-rate brachytherapy. A radium-224/Pb-212 generator similar to the Mo-99/Tc-99 one enables the Pb-212 to be eluted as required for targeted alpha therapy (TAT). An earlier proposal for Mo-99 production involving an innovative reactor and separation technology has lapsed. For targeted alpha therapy (TAT), actinium-225 is used, from which the daughter bismuth-213 can be obtained (via three alpha decays) to label targeting molecules. The thyroid, bones, heart, liver, and many other organs can be easily imaged, and disorders in their function revealed. Tracer, with longer life than F-18, one-quarter of decays are positron emission so used with PET. In particular, they are central to the fields of nuclear medicine and radiotherapy. Application of sealed radioisotopes/radiation in industry THICKNESS MEASUREMENT AND CONTROL: The 0.54 MeV beta of Sr (90) is used for measuring thickness- back scattering technique. They contain molybdenum-99 (Mo-99), with a half-life of 66 hours, which progressively decays to Tc-99. Demand is increasing. Much of the Co-60 is supplied through Nordion. Nuclear reactors have provided us with valuable radioactive atoms (radioisotopes) for use in research and industry, and they have given us cheap, clean power, which can drive a ship around the world on a tiny charge of fuel.
