In 1974, the USSR launched the biosatellite Cosmos-690 equipped with a gamma-irradiation unit that carried 35 rats. On the 10th flight day, the rats were exposed to radiation at doses of 220 or 800 rads. During the subsequent 10 d, radiation injury developed in a space environment. Similar ground-based experiments were carried out to simulate space flight environment effects. The results obtained were studied on a comparative basis. The conclusion is made that effects of a short-term space flight, as long as 20 d, do not essentially modify the radiobiological effect.
1974年，苏联发射了搭载伽马辐射装置的生物卫星“宇宙-690号”，卫星上搭载了35只大鼠。在飞行第10天，这些大鼠受到了220拉德或800拉德剂量的辐射。在随后的10天里，辐射损伤在太空环境中出现。还进行了类似的地面实验以模拟太空飞行环境的影响。对所获得的结果进行了对比研究。得出的结论是，长达20天的短期太空飞行的影响并没有从本质上改变放射生物学效应。
