The effect of exposure rate on translocation induction in spermatogonia, scored as multivalents in descending spermatocytes and bone-marrow cells of the mouse (Mus musculus) was investigated 65--100 days after X-ray and gamma-ray exposures of 400 R. In the range of exposure rates studied there was a decreased in frequency in bone-marrow cells from 17.1% at 130 R/min to 4.6% at 0.0287 R/min. In spermatogonia the frequency dropped from 6.7% at 130 R/min to 1.9% at 0.0287 R/min. The data obtained for both tissues fitted a straight line when plotted against the logarithm of the exposure rate. The ratios between aberration frequencies in bone-marrow cells and spermatogonia, with a mean value of 2.74, were independent of exposure rate.
在对小鼠（小家鼠）进行400伦琴的X射线和γ射线照射65 - 100天后，研究了照射率对精原细胞易位诱导的影响，易位通过减数分裂后期精母细胞和骨髓细胞中的多价体来计分。在所研究的照射率范围内，骨髓细胞的频率从130伦琴/分钟时的17.1%下降到0.0287伦琴/分钟时的4.6%。在精原细胞中，频率从130伦琴/分钟时的6.7%下降到0.0287伦琴/分钟时的1.9%。当针对照射率的对数进行绘制时，两个组织获得的数据均符合一条直线。骨髓细胞和精原细胞中畸变频率的比值平均值为2.74，且与照射率无关。
