This publication should be useful for those who are interested in the theory and application of isotopes and radiation in agriculture and entomology. There are two main parts in the publication. Part I, entitled Basic Part, includes topics which an individual should know about radioisotopes and radiation. There are laboratory exercises included in this section. Some of the topics included are energy of radiation, autoradiography, health physics; docontamination, and activation analysis. Part II, entitled Applied Part, consists of detailed laboratory exercises in the use of isotopes and radiation in entomology. The publication should be useful for conducting training programs in this field. (PS)
