RESEARCH OBJECTIVES
Matroshka-2A measures the radiation dose distribution of crew members inside the
International Space Station (ISS). Matroshka-2A combined with data from Matroshka-1 allows
the comparison of skin and depth dose measurements performed with the same facility inside
and outside the International Space Station. 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.
