MATROSHKA
MATROSHKA (MTR) Facility is designed to determine the radiation exposure of an astronaut / cosmonaut during an extravehicular activity (EVA) (MTR-1) and during his stay inside the International Space Station (MTR-2 A/B)
Radiation exposure is measured in a Phantom simulating an Human Upper Torso shielded with a Carbon Fibre structure simulating the EVA suit
Active and Passive Radiation Detectors are distributed over the whole body to determine skin and organ doses
MATROSHKA inside ISS January 2004

MATROSHKA
MATROSHKA-1 was the first long duration phantom experiment positioned outside a Space Station(Duration of ~ 600 days)
MATROSHKA-2 A/B will measure the dose distribution of an astro – and cosmonaut inside the ISS
The combination of MTR-1 and MTR-2will for the first time allow the comparison of skin- and depth dose measurements performed with the same facility in and outside the ISS
Results will give the dose distribution inside a Human Phantom for a better correlation between skin and organ dose and for better risk assessment in future long duration space flight
MATROSHKA-1 EVA February 2004
