RESEARCH OBJECTIVES
Matroshka-Kibo continues to measure the radiation dose distribution of crew members inside
the International Space Station (ISS) and specifically in the Japanese Kibo laboratory.
Matroshka-Kibo combined with data from Matroshka-2A and -2B allows to spot and to quantify
differences in the radiation environment in three crew locations on the ISS (MTR-2A: Pirs, MTR-
2B: Zvezda, MTR-Kibo: Kibo).
RESULTS
For Matroshka-Kibo, the phantom from MTR-1/MTR-2A/MTR-2B was used again, but fitted with
a fresh set of passive detectors. The passive detectors were installed inside the Matroshka
phantom for 10 months between May 2010 and March 2011 with the facility taking
measurements from its location within the Japanese Kibo laboratory. Publication of results is
currently under preparation.
