An investigation and research is reported into the radiation environment of a geostationary satellite and the radiation resistance of quartz resonators to be installed in artificial satellites. The total absorbed dose of a synchronous satellite in a geostationary orbit reaches about 1*104 Gy in ten years. For example, the rate of change of the frequency of a quartz resonator manufactured from an unswept crystal with a Q-value of about 2.8 million was about 0.2*10-6 at a total absorbed dose of 1*105.
