Abstract The authors report about comparative investigations on the induction of mutations in Drosophila by fast electrons of a betatron and by conventional x rays. The rates of ray-induced sex-linked recessive lethal mutations were determined by means of the Muller-5-(Basc) method. Under the described conditions of equivalent doses (4000 and 2000 r Fesp. rep) 15 Mev electrons and 200 kv x-rays were found to produce the same mutation rates within the range of statistical error. The relative biological effectiveness of the betatron electrons is approximately 1. (auth)
