This report covers a number of the applications of isotopes and radiation to the fundamental problems of biology. It clearly demonstrates the value of using the newly acquired tracer technics as supplements to the standard methods of research in the life sciences. The individual reports are written by various authors, all well qualified in their respective fields.
The report is of special value because it reviews and summarizes much of the recent information on the chemical and physiologic effects of ionizing radiation. These include discussions such as on the effect of ionizing radiations on aqueous solutions, an enzyme preparation and on the organism as a whole. A discussion of the use of ionizing radiations and ultraviolet rays affecting the general problem of the nature of gene action is included. The reviews of some of the applications of radioactive isotopes of iron, phosphorus and carbon in studies of intermediary metabolism are
