RESEARCH OBJECTIVES
Study of the Depth Dose Distribution Inside a Human Phantom Using the Matroshka Facility
Onboard the Russian Segment of the International Space Station (Matroshka-2B) is a
continuation of Matroshka-2A investigation that studies the radiation dose distribution of crew
members inside the International Space Station (ISS). The combined data from all Matroshka
investigations allows the comparison of skin and depth dose measurements performed with the
same facility inside and outside the ISS. The results will give the radiation dose distribution
inside a human phantom torso for a better correlation between skin and organ dose and for
better risk assessment in future long duration spaceflight.
