Abstract: Pille was developed as the first and to date the only thermoluminescent dosimeter system containing on-board reader designed specifically for spacefaring humans. Since its very first launch in 1980, the Pille system has been providing space radiation measurements from aboard almost every space station (Salyut-6, -7, Mir, International Space Station (ISS)). It has been continuously used on board ISS since October 2003 under the supervision of the Institute for Biomedical Problems (IBMP) as an essential part of the service dosimeter system of the Russian Zvezda module. In the past 21 years the dosimeter system was utilized for routine dose measurements inside the ISS and during Extra-vehicular Activities (EVAs). The Pille system consists of a lightweight reader device and a number of TL dosimeters (CaSO4:Dy). It provides monthly dose data obtained in different locations of the Russian module. Three dosimeters are dedicated to EVA measurements (two for the astronaut pairs, one inside the ISS for reference), and one is read out in every 90 minutes automatically to provide high time resolution data. In June 2022, a modified Pille-ISS dosimeter was introduced on board the ISS for EVA measurements and cross-calibrated with the standard Pille-ISS dosimeters. In the case the modified dosimeters, the technical modifications allowed reducing the excessive local shielding of the TL crystals, making it possible to be sensitive to electrons and protons with lower energies. In our presentation the latest results (including several EVAs) and the assessment of the results of the new type of Pille-ISS dosimeters and the on-board cross-calibrations will be detailed, together with comparisons of data from different missions
