The report contains the description of the devices used for studying the radiation environment in space. They consist of passive dosimeters, a monitoring dosimeter and a spectrometer. Data were obtained with them over a long period of time. The analysis of these data permits one to conclude that radiation dose greatly depends on the apogee altitude and inclination; increasing the shield thickness does not greatly decrease the daily dose. The daily doses in orbits with an inclination of less than 65 degrees are 7 to 45 mrad day-1; the quality factor in those orbits was 1.2-1.4.
