Portrays the mutation effect of high-energy radiation as resulting from effects produced by means of ionization. Explains how ions can produce mutation. Discusses the measurement of X-ray dosage in roentgens and the dosage required to double the spontaneous mutation rate in Drosophila, mice, and man. Points out similarity of radiation-induced and spontaneous mutation. Explains the magnitude and meaning of permissible doses of high-energy radiation and discusses other mutagenic agents (ultraviolet light and chemical substances), concluding with comments on the importance of gene mutation to present and future generations. Lecture given by Dr. H. J. Muller.
