abstract: In the report of the Committee on Genetic Effects of Atomic Radiation, which appeared in the 29 June issue, the number "200 million children" in line 18 of the third column on page 1163 is an error. The question should read: "What is the estimate of the total number of mutants which would be induced by this radiation dose and passed on to the next total generation of about 100 million children?"
