    Abstract:
    The yield of translocations induced by acute gamma-irradiation at low doses (0.25 and 0.50 Gy) in the crab-eating monkey's (Macaca fascicularis) spermatogonia was examined. The frequencies of translocations per cell were 0.53% at 0.25 Gy and 1.07% at 0.50 Gy. Over the low dose range from 0 to 1 Gy, the dose-response relationship for translocation yield was a linear one with a regression coefficient of 1.79 X 10(-2). To estimate the sensitivity to the induction of translocations in the crab-eating monkey's spermatogonia, the slope of the regression line was compared with those in other mammalian species. Consequently, over the low dose range below 1 Gy, the sensitivity of the crab-eating monkey's spermatogonia to translocation induction was similar to several mammalian species, the mouse. Chinese hamster, and the rabbit, but significantly higher than that of the rhesus monkey and lower than that of the marmoset.
