Developmental capacities of Artemia eggs have been studied after exposure to 645 MeV or 9.2 GeV protons. Effects of proton irradiation were studied in comparison with 60Co gamma ray irradiation, endpoints being emergence, hatching and 4-5 day old live nauplii percentages. Effectiveness of 645 MeV protons is greater than that of 9.2 GeV protons. R.b.e. values calculated for nauplius survival is 2.3 for 645 MeV protons and 1.5 for 9.2 GeV protons. These results can be taken into account in radiation hazard estimation during space flights.
卤虫卵在暴露于645兆电子伏特或9.2吉电子伏特质子后，其发育能力已得到研究。将质子辐照的影响与60Coγ射线辐照进行了比较研究，终点指标为孵化率、孵化出膜率和4 - 5日龄活无节幼体百分比。645兆电子伏特质子的有效性大于9.2吉电子伏特质子。计算得出，对于无节幼体存活，645兆电子伏特质子的相对生物效应值为2.3，9.2吉电子伏特质子为1.5。在估算太空飞行期间的辐射危害时可考虑这些结果。
