Scientific paper

Cosmic flights always imply the penetration into a new radiation climate alien to life on earth. This is expressed both in the higher values of the radiation dose to be expected and in the deviation of the type and spectral distribution of cosmic radiation in space from terrestrial radiation. For the dosimetry of cosmic radiation onboard spacecraft, this results in two tasks. First, the radiation exposure of the astronaut onboard is to be detected and, secondly, the influence of radiation on the proper functioning of equipment and materials on and in the spacecraft is to be determined. The radiation measuring technique used for this purpose has to supply statements on the radiation doses, types of radiation and their expected spectral distribution. Based on the known effectiveness of radiation as a function of its type and energy, it is possible to derive risks and possible protective measures. The overall goal of this project was to carry out further research of the dynamic radiation situation in near space by means of passive radiation detectors. The project was broken down into the following topics: (1) determination of the depth dose distribution of primary cosmic radiation behind thin screens outside spacecraft; (2) detection of the neutron energy distribution and neutron dose inside spacecraft; and (3) interpretation of the readings of TL detectors and solid-state trace detectors inside spacecraft.
