Radioactive decay medical applications

Once radioactive decay starts, it continues until all the atoms have reached a stable state. The radioisotope can only be shielded to prevent exposure to the radiation. The most common applications of gamma rays are sterilization of single-use medical supplies, elimination of organisms from pharmaceuticals, microbial reduction in and on consumer products, cancer treatment, and processing of polymers (cross-linking, polymerization, degradation etc.). 

Although the uptake of by the thyroid gland was a health risk after the Chernobyl disaster (Box 2.2), controlled uptake has medical applications. If a patient ingests l (e.g. as a solution of l-labelled Nal), the isotope is quickly absorbed by the th5Toid gland and the size and state of the gland can be detected by monitoring the radioactivity emitted. For l, ri 8 days, and the dose administered soon decays. 

Nuclear chemistry is the study of nuclear reactions, with an emphasis on their uses in chemistry and their effects on biological systems. Nuclear chemistr) affects our lives in many ways, particularly in energy and medical applications. In radiation therapy, for example, gamma rays from a radioactive substance such as cobalt-60 are directed to cancerous tumors to destroy them. Positron emission tomography (PET) is one example of a medical diagnostic tool that relies on decay of a radioactive element injected into the body. 

Chapters 16 (waste disposal). Chapter 17 (radioactive materials transportation), and Chapter 18 (decontamination and decommissioning) are related to many radioactive processes and materials. Radioactive waste is generated wherever radioactive materials are handled and used. This includes medical applications of radioactive isotopes and their production, as well as the facilities and processes involved in nuclear power. This waste must be stored and/or disposed of in a way that isolates it from the environment until the radioactive materials decay. 

In addition to the normal and binomial distributions, there are others that are better suited to other purposes. In medical and biological research, the Poisson distribution is useful in expressing the distribution of organisms in a sample. For example, the hemocytometer enables the number of red corpuscles to be counted in each of a number of small volumes when observed under the microscope. Forthese particular applications, the Poisson distribution is useful. The Poisson distribution is also employed in nuclear physics involving the extent of radioactive decay in a given interval of time. It is also used in agricultural research.
