Induction of Mutations in Mice by Chronic Gamma Irradiation; Interim Report

Abstract
Wild-type male mice given 40 r of [gamma] irradiation were mated with non-irradiated females homozygous for 7 recessive mutants. The object of the experiment was to test for non-linearity of the mutation-rate/radiation dose law. So far, one mutation in 10,000 irradiated mice and two mutations in 18,000 control mice have been found.
