Some of the studies on late effects of neutron and gamma radiation previously carried out with the C57BL6 X BALB/c F1 hybrids of Mus musculus have been repeated with the white-footed mouse, Peromyscus leucopus, a cricetid rodent of a different subfamily, with differing physiological characteristics and a different spectrum of pathologies. Among the more important findings were the following: For both species, the life shortening per rad at low doses of either radiation was the same percentage of the life span. The limiting values of the relative biological effectiveness for life shortening from all causes of death were about the same for the two species, ranging from 8 to 16, depending on the method of calculation. Fractionated neutron exposures failed to produce significant life shortening in Peromyscus over that observed at single doses. Tumor-related deaths accounted for at least 70 to 75% of the radiation-specific excess mortality in Peromyscus.
先前使用小家鼠的C57BL6 X BALB/c F1杂种对中子和γ辐射的晚期效应进行的一些研究，已对白足鼠（白足鼠属，属于不同亚科的仓鼠科啮齿动物，具有不同的生理特征和不同的病理谱）重复进行。其中一些更重要的发现如下：对于这两个物种，低剂量辐射下每拉德的寿命缩短占寿命的百分比相同。两种物种因各种死因导致寿命缩短的相对生物效应的极限值大致相同，根据计算方法的不同，范围在8至16之间。分次中子照射对白足鼠的寿命缩短作用并不比单次照射时显著。在白足鼠中，与肿瘤相关的死亡至少占辐射特异性额外死亡率的70%至75%。
