用三种放射性核素~(137)Cs、~(131)I和~(32)P(海水),分别浸泡贻贝和马粪海胆的精子、卵子和受精卵的不同发育阶段,将各试验组所得结果与对照组相比,没有发现低浓度放射性核素(10~(-10)居里/升),对试验动物的受精作用和胚胎发育有不利的影响。一般来说,发生不利影响(如发育成幼虫的百分率降低等)的放射性核素要高至10~(-4)居里/升。试验的初步结果支持Brown和Templeton的看法,即不能把个别试验组与对照组的差异说成是放射性核素影响的结果。
The three kinds of radionuclides 137 Cs, 131 I and 32 P (seawater) were used to immerse the sperm, eggs and fertilized eggs of mussels and horse dung, The results obtained in the group compared with the control group, found no low concentrations of radionuclides (10 ~ (-10) Curie / liter) on the fertilization of experimental animals and embryo development have a negative impact. In general, radionuclides that are adversely affected (such as reduced rates of development into larvae) should be as high as 10 -4 Curie / liter. Preliminary results of the trial support Brown and Templeton’s view that the difference between individual test and control groups can not be described as the result of radionuclide effects.
