title: [Basic purposes and results of a radiobiological experiment on the "Kosmos-690" biosatellite].
abstract: In 1974 the USSR carried out a rat experiment aboard the biosatellite Cosmos-690 equipped with a gamma-emitter. On the 10th flight day rats were irradied with doses of 220 and 800 rad. During the subsequent 10 days radiation damage developed. Similar experiments simulating the flight profile, except for weightlessness, were conducted on the Earth. The resulting data were compared. It is concluded that a short-term (up to 20 days) flight did not modify essentially the radiobiological effect.
