Progress beyond the State of the Art

MATROSHKA is the first experiment that uses a simulated human head/torso for the measurement of the skin dose and the depth dose distribution, both outside and inside the ISS. A similar torso-phantom provided by NASA was flown in 2001, but only inside the space station and for a limited period of time in the year 2001. Unfortunately the experiment was only partly evaluated and therefore only limited data is available to the scientific community.

In contrast, the ESA MATROSHKA experiment offers for the first time:

  • Measurement of the radiation load on a simulated human torso outside the space station (MTR 1)
  • The analysis and comparison of the outside measurement with data from inside exposures (MTR 2A and 2B)
  • The full availability of the experimental data from the co-investigators of the experiment.
  • The construction of a 3D model of the dose distribution in the phantom based on the experimental data, and a comparison with the dose distribution obtained from radiation transport calculations. Together, the experimental and calculated dose distributions will lead to a more accurate description of the radiation environment for personnel inside and outside space vehicles, and better risk estimations for future long duration space flights.

These aims are achieved by a well established and strong cooperation of European partners within the HAMLET project.
