Abstract：
In order to measure the radiation dosimetry by heavy ions which entered the Shen-Zhou (SZ) shuttles, a solid state nuclear track detector CR-39 was installed in the inner wall of SZ recoverers. Using a CR-39 detector the energy transfer from heavy ions was measured when the shuttle was travelling in space. This work described a calibration of the response of CR-39 detector to the energy deposition using 9 ion accelerator beams from C to Kr. The calibration points cover the whole sensitive region of the CR-39 detector. For the linear energy transfer (LET ) is larger than 12.6 keV/μm-H2O, the total absorbed dose of SZ-3 and SZ-4 are obtained to be (23.50±0.46) μGy and (35.34±1.57)μGy , respectively, the corresponding total dose equivalent are obtained to be (355.6±9.7) μSv and (574.4±15.6)μSv，respectively.
