Аннотация: The EXPOSE-R2 experiment was carried out by the European SpaceAgency on board “Zvezda” module of the ISS. The R3DR2 device was one amongthe EXPOSE-R2 instruments. The semiconductor detectors were sensitive elementsof the R3DR2 device that permit to measure radiation doses behind thin shielding.The results of this experiment are freely available now.We used them to analyse variationsin the radiation environment at ISS altitude in the Earth’s outer radiation belt.SINP MSU carried out a similar experiment on board The “Lomonosov” satellite.One of its devicesDEPRONinstrument includes semiconductor detectors. The detectorswere similar in design to those in the R3DR2 instrument. The analysis showedthe presence of significant enhancements in dose rate. The dose rate of such enhancementsreached the level of 28.8 mGy/h according to R3DR2 data and 106.5 mGy/haccording to DEPRON data. However, the total dose rate of single enhancements didnot exceed 0.8 mGy according to R3DR2 data and 1.6 mGy according to DEPRONdata. Comparison with geomagnetic conditions showed that such enhancements areobservedmainly during periods of geomagnetic disturbances. The obtained informationmay be used to estimate the level of radiation impact in the region of the Earth’souter radiation belt.
