.What is radioactivity? What are the applications of radioisotopes?
Radioactivity is defined as the spontaneous emission of radiation in the form of particles or high-energy photons that are a result of a nuclear reaction. It is the release of energy from the decay of the nucleus of atoms and/or isotopes. Applications of radioisotopes: ● The isotope of Co 60 − emits -radiation that is used to treat cancer. ● I 131 − is used in the diagnosis and treatment of thyroid gland diseases. ● P 32 − is used in the treatment of leukemia and the identification of malignant tumors. ● C 14 − is used to study biochemical processes.
