Drosophila melanogaster males were exposed to a homogeneous magnetic field of 7500 gauss to determine whether such exposure would affect in any way 2000R X-irradiation induced genetic damage. The X0 method was used to detect breakage of X and Y chromosomes. A second series of experiments was designed to ascertain the developmental effects of: 1. A magnetically quiet environment. 2. Homogeneous fields of 150, 300, and 7500 gauss. 3. An inhomogeneous field of 7500 gauss(1500 gauss/cm). Seventy-five hundred gauss had an observable effect upon 2000R X-irradiation induced genetic damage. An increased rate resulted. Developmentally, the results indicated that a magnetically quiet environment promoted growth and favored an increased frequency of females. Seventy-five hundred gauss produced an increased frequency of males and retarded the growth of larvae. No observable effects were noted for fields of 150 and 300 gauss, nor for the inhomogeneous field of 7500 gauss.
