The combined effect of weightlessness and ionizing radiation (24 hour exposure to Cs-137 at a total dose of 800 rad) was investigated morphologically in Cosmos-690 flight, synchronous and vivarium rats. Irradiation-induced lesions prevailed in both groups of rats. Comparative study of changes in flight and control rats showed that weightlessness and other space flight factors did not induce any new, previously unknown effects as compared with the exposure on the Earth; they did not exert a significantly aggravating effect on the development of radiation-induced lesions.
在“宇宙-690”号飞行实验中，对处于失重和电离辐射（24小时暴露于铯-137，总剂量为800拉德）联合作用下的航天大鼠、同步对照大鼠和地面饲养大鼠进行了形态学研究。两组大鼠均以辐射诱发损伤为主。对飞行大鼠和对照大鼠的变化进行比较研究表明，与在地球上接受照射相比，失重和其他太空飞行因素并未引发任何新的、先前未知的效应；它们对辐射诱发损伤的发展也没有显著的加重作用。
