To evaluate the impact of space radiation on human health and to reduce the uncertainty of related cancer risk, it is important to determine the exposure level as accurately as possible. Due to complexity of radiation environment in space and behind the shielding, accurate data cannot be obtained using only calculations. Experimental measurements in real flight conditions are also necessary.
In this contribution we present results obtained during two space missions - onboard International Space Station (during 2012-2013) and onboard biosatellite BION-M1 (April May 2013). In both cases, packages containing thermoluminescent and plastic nuclear track detectors were placed at various locations onboard ISS/BION-Ml. Spectra of linear energy transfer, absorbed doses, and dose equivalents are discussed with respect to orbit parameters and shielding.
For both missions, dose characteristics can differ by a factor of about 2, depending on the location. Due to higher altitude and limited shielding, absorbed dose and doe equivalent inside BION-Ml are significantly higher than inside 'ISS - whereas inside ISS the maximal value of measured dose equivalent rate was about 1 mSv/day, inside BION-M1 it exceeded 3 mSv/day. Outside the capsule it was about two times higher than inside the capsule.Pracoviště Ústav jaderné fyziky Kontakt Markéta Sommerová, sommerova@ujf.cas.cz, Tel.: 266 173 228 Rok sběru 2018
