ANALYTICAL METHOD FOR DETERMINING TRANSMISSION AND ABSORPTION OF TIME-DEPENDENT RADIATION THROUGH THICK ABSORBERS III - ABSORBER WITH RADIOACTIVE DAUGHTER PRODUCTS

摘要

A theoretical treatment of absorption problems is presented in which the following cases are simultaneously considered:n(a) Radiation is normal to an absorber of which the stations are plane parallel Surfaces.n(b) Radiations are of several polyenergetic types.n(c) Indeced radioactive isotopes decay to stable atoms in multistep decay processes.n(d) Radiations from the absorber affect the time-dependency of the source activity.
