Matroshka-R Phantom experiment

ISS014-E-09097 (December 2006) --- European Space Agency (ESA) astronaut Thomas Reiter, Expedition 14 flight engineer, works with the European Matroshka-R Phantom experiment in the Zvezda Service Module of the International Space Station. Matroshka, the name for the traditional Russian set of nestling dolls, is an antroph-amorphous model of a human torso designed for radiation studies. The activity, supported by ground specialist tag-up, requires equipping the torso's individual horizontal slice-like layers with 356 thermo luminescent detectors (TLDs) and five nuclear radiation tracking detectors (NTDPs). The mannequin was then to be reassembled, covered with poncho and hood and installed in the Pirs Docking Compartment for studies of on-orbit radiation and long-term dose accumulation.
