Space radiation dosimetry

In this report dosimetric measurements are presented which were performed during the missions Spacelab 1, D 1, Biocosmos 8 and Biocosmos 9. Detector packages consisting of plastic nuclear track detectors, nuclear emulsions and thermoluminescence dosimeters were exposed at different locations inside and outside spacecrafts behind more or less well defined 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 equivalents for the astronauts have been calculated from the measurements using the quality factors as defined in the old and the new recommendations of the International Commission on Radiation Protection (ICRP).
