Radioisotopes are frequently used as tracers or tagged atoms in various fields. In tracer technique, a radioactive isotope is added to the reactants and its movement is studied by measuring radioactivity in different par..

g - rays emitted by the radioisotopes can be used in the treatment of cancer. These radiations tend to destroy cancerous cells and the way can arrest the spreading of the cancerous cells. 6 0 CO is used in the treatment of tumours and cancers...

Radioactive phosphorus (P 3 2 ) is used in the study of metabolism of plants. Radioactive sulphur (S 3 5 ) helps to study advantages and disadvantages of fungicides. Pests and insects on crops can be killed by - radiations., - rays are used for preservation of ..

Positron Emission Tomography (PET) - PET is a sophisticated version of radio isotope scanning. The principle behind PET scanning is as follows. Short - lived radio isotopes such as 1 1 C, 1 3 N or 1 5 O are produced and incorporated into a solution (of glucose) that can be injected into the body. A..

Radioactive Dating - All radioactive decays follow first order kinetics. Therefore, the half-life of a radioactive element is independent of the amount of sample. With the help of half-life values of a suitable radioisotope of an element, which is present in a rock, or in an artefact, the..

Nuclear changes can be brought about by bombardment of nuclei with accelerated particles like neutrons, deuterons and protons. A particularly important process for the production of artificial radioactive isotope is the (n, g ) reaction, which is applied to synthesize new elements. Units o..
