Apathy 1 German Aerospace Center (DLR), Cologne, Germany 2 KFKI Atomic Energy Research Institute, Budapest, Hungary Abstract: The Dosimetric Mapping (DOSMAP) experiment, operated by Expedition Two onboard the ISS attempted to record and map radiation inside Space Station within a four month period. One of the several different types of devices used by DOSMAP was the Passive Dosimeter System (PDS) containing twelve pieces of TLD-PNTD (ThermoLuminescent Dosimeter and Plastic Nuclear Track Detector) kits and an onboard TLD Reader. The TL Dosimeters of the kits, located at different places on ISS were read out and evaluated periodically on board. One TLD was permanently inserted in the Reader and read out every 1.5 hours automatically to achieve an extremely good dose rate time resolution at that location. Preliminary results of the TLD measurements are presented in this report. The LET dependence of the TLD efficiency will be corrected using LET spectra recorded by the PNTDs.
