It is a study of radioactive materials, where the isotopes of elements are used to study the properties and chemical reactions of non-radioactive isotopes and deals with the use of radioactivity to study ordinary chemical reactions is Radiochemistry. Radioactivity is present ever since the formation of the earth. The subject of radiochemistry is introduced with a discussion of the three principal naturally occurring radioactive series of substances. A discussion of atomic and nuclear structure is followed by an excellent treatment of nuclear reactions. Radiochemistry differs from radiation chemistry where the radiation levels are kept too low to influence the chemistry. Radiochemistry includes the study of natural and man-made radioisotopes.
