radioisotope. a radioactive form of an element, consisting of atoms with unstable nuclei, which undergo radioactive decay to stable forms, emitting characteristic alpha, beta, or gamma radiation. These may occur naturally, as in the cases of radium and uranium, or may be created artificially.
Autoradiography not only permits the definition of the radioisotopeâs localization in a biological object but also helps to find the quantity of the radioisotope, since the number of reduced silver grains in the emulsion is proportional to the number of particles reacting with the emulsion.
