Simian virus-40, polyoma, and LLE46 virus preparations were treated with ultraviolet or gamma radiations (cobalt-60) in a frozen state. Infectivity and induction of complement-fixing antigen and DNA synthesis declined as a logarithmic function of dose, the latter two properties being more resistant than infectivity to radiation by a factor of 2 to 5. Oncogenicity of all three viruses did not decrease with progressive amounts of both types of irradiation, but actually increased in absolute and relative terms (per infectious unit), even at the maximum dose of irradiation used (24,000 ergs per square millimeter per minute and 2.7 x 10(6) rads).
猿猴病毒40、多瘤病毒和LLE46病毒制剂在冷冻状态下用紫外线或γ射线（钴60）处理。感染性以及补体结合抗原的诱导和DNA合成随剂量呈对数函数下降，后两种特性比感染性对辐射的抵抗力强2至5倍。随着两种辐射剂量的增加，所有三种病毒的致癌性并未降低，实际上在绝对值和相对值（每感染单位）上都有所增加，即使在所用的最大辐射剂量（每分钟每平方毫米24,000尔格和2.7×10⁶拉德）下也是如此。
