[Calculation of radiation loads onto cosmonauts during extravehicular activities on the International space station].
A geometrical spacesuit model was developed to assess shielding functions of the human body systems and organs. The shielding functions of specific points inside the spacesuit determined with the help of the geometric human body model were compared with the published data from experiments with the Russian Orlan-M spacesuit. Provided a good agreement of the results, shielding of specific organs and systems within the human body geometrical model were calculated. Periods of the ISS EVAs in the Russian spacesuits during 2001-2006 were analyzed to estimate the absorbed doses and quality factor for the body organs and systems. Methods for calculating the absorbed doses from the data of EVA dosimeters are proposed.
