Interaction between mutagenic effects of strong homogeneous magnetic fields and fission neutron-plus-gamma radiation was investigated, using the sex-linked, recessive, lethal test in Drosophila melanogaster. Drosophila males were exposed chronically, for seven days, to a 37,000-G homogeneous magnetic field and/or 3 doses of neutron-plus gamma radiation. Mutations in spermatozoa, spermatids, and spermatocytes were scored. There was no evidence of interaction between the effects of the two types of exposure in causing genetic damage in any of the three cell types. Dose-response relations for the radiation doses were linear for spermatozoa and spermatids for all three doses and for spermatocytes, up to 300 rads. Spermatozoa appear to be most sensitive to neutron-radiation-induced, recessive lethal mutations.
利用果蝇的性连锁隐性致死试验，研究了强均匀磁场的诱变效应与裂变中子加γ辐射之间的相互作用。将果蝇雄性长期暴露于37000高斯的均匀磁场和/或3种剂量的中子加γ辐射下7天。对精子、精细胞和精母细胞中的突变进行了评分。没有证据表明这两种暴露效应在三种细胞类型中的任何一种中导致遗传损伤时存在相互作用。对于所有三种剂量，精子和精细胞的辐射剂量反应关系呈线性，对于精母细胞，剂量高达300拉德时呈线性。精子似乎对中子辐射诱导的隐性致死突变最为敏感。
