根据美国毒理研究机构提出的持续繁殖实验的方法，观察高本底放射性饮水对小鼠生育力及仔鼠生长发育的影响。观察指标包括受孕率、每窝生胎鼠数、生育平均间隔天数、死胎畸胎数及仔鼠生长发育各种指标等。结果显示：高本底放射性饮水对实验动物生育力和胎鼠生长发育水平表现出一定的促进作用，其余检测指标均无统计学意义。
According to the method of continuous reproduction experiment proposed by the U.S. Toxicological Research Institute, the effects of high background radioactive drinking water on the fertility of mice and the growth and development of pups were observed. Observational indicators include the pregnancy rate, the number of embryos per litter, the average number of days between births, the number of stillbirths and the growth and development of pups. The results showed that high background radioactive drinking water had a certain promotion effect on the fertility of experimental animals and the growth and development of fetal rats, and the rest of the detection indicators had no statistical significance.
