SPACE RADIATION-DOSIMETRY

In this report dosimetric measurements are presented which were perfor med during the missions Spacelab 1, D 1, Biocosmos 8 and Biocosmos 9. Detector packages consisting of plastic nuclear track detectors, nucle ar emulsions and thermoluminescence dosimeters were exposed at differe nt locations inside and outside spacecrafts behind more or less well d efined shielding thicknesses. These detector systems, which supplement each other in their registration characteristic, allow to record all biological relevant portions of the radiation field separately. Dose e quivalents for the astronauts have been calculated from the measuremen ts using the quality factors as defined in the old and the new recomme ndations of the International Commission on Radiation Protection (ICRP ).
