Anticipated use of extremely large magnets in future, controlled thermonuclear reactors and occasional exposures in various occupational and research environments both require that biological effects of these fields be investigated. The genetic effects of high magnetic field intensities ranging from 13,000 to 37,000 G, using Drosophila melanogaster have been investigated. Results from these experiments provided no evidence of a statistically significant increase in the frequency of sex-linked, recessive, lethals in adult Drosophila males. However, since ionizing radiation - both gamma and neutron - also may be present in the vicinity of controlled thermonuclear reactors and high-energy accelerators, it is important to test for possible interaction (synergistic or antagonistic) between radiation and magnetic field effects. Such interaction was studied by Close and Beischer for mean life span and by Mittler for sex-linked recessive lethals, using low magnetic field intensities and short exposure periods in these experiments, much longer exposures, stronger fields, and a combination neutron and gamma radiation exposure are employed.
