- Abstract
The article presents the first attempt to analyze data obtained simultaneously by the Russian BTN and Bulgarian R3DR instruments, flown in 2010 on the Zvezda module of the International space station (ISS). Both instruments have well established sensitivity against gamma radiation. This was verified in space, when the Russian spacecraft Soyuz TMA-16, initially docked to the aft port of the Zvezda module, was relocated to the zenith-facing port of the Poisk module on January 21, 2010. This maneuver brings a gamma ray source in the angle of view of both the BTN and R3DR instruments. The comparison of the data, after the relocation, for the first channels of the spectrometers reveals that they are elevated. This situation continues till March 18, 2010 when Soyuz TMA-16 spacecraft was undocked from the ISS and landed. The final part of the paper, investigate the decrease of the R3DR instrument dose rates in the region of the South Atlantic anomaly (SAA), generated by the additional mass of the Soyuz TMA-16 spacecraft.
