✦ Synopsis
To determine whether a 50-Hz magnetic field will induce mutations, a sex-linked recessive lethal test of Drosophila rnekunoguster was performed. Adult flies were exposed at an rms flux density of 500 FT or 5 mT to the homogeneous field of a Helmholtz coil. The ambient field to which controls were exposed was less than 1 pT. Exposures took place continuously for 13 to 14 days, which correspond to the life cycle of Drosophilu at 25 "C. About 10,000 X-chromosomes were tested at each flux density. Recessive lethal mutation rates of 0.13, 0.21, and 0.18 percent were observed, respectively, for control, 500-pT, and 5-mT conditions. By the Kastenbaum-Bowman significance test, the recessive lethal mutation rates in the 500-pT and 5-mT conditions did not differ from the mutation rate of controls.
