title: [Method of irradiating bioobjects and results of dosimetric measurements on the biosatellite "Cosmos-690"].
abstract: The paper describes the design and experimental conditions of rat irradiation aboard the biosatellite Cosmos-690. An essential dose gradient due to different distances between the gamma-source and irradiated rats as well as due to the presence of construction components and equipment in the beam was made up by a special dose-equilibrating filter. The spectral distribution of scattered radiation reached maximum in the region of 0.1--0.3 Mev. The average dosage in the location of the main group of animals was 800 +/- 85 rad and that in the location of an additional group was 220 +/- 25 rad.
