| 内容記述 | We conducted the radiation monitoring experiment for passive radiation dosimeters as a part of the BRADOS experiment on the International Space Station (ISS) in 2004. Five dosimeters boxes with passive detectors from IMBP and NIRS were exposed on the Russian segment of the ISS during the period of the BRADOS II space experiment sessions from Jan. 29 to Oct. 24 in 2004. The dosimeter package consists of LiF TLDs, Glass detectors and CR-39 detectors with some Al targets. In this study, we employed CR-39 detector named HARZLAS TD-1 and verified the variation of LET spectra by several bulk etch conditions (multi-step) from 5 - 53 m at the same position of a TD-1 detector. All etch pit was traced at each step of etching time as shown in Figure. Many high LET particles with short range are observed in the CR-39 detector, which are considered to be produced by target fragmentation reaction with high energy proton. They make a significant dose effect in inner body (e.g. bone consisting of Ca). In this talk, the preliminary results on variation of dose quantities obtained by the CR-39 detector will be presented. | |||||
