| 内容記述 | The dose reduction rate for space radiation by the additional installation of water shielding (the hygienic wipes and towels containing water) in ISS crew cabin was measured with the passive dosimeter packages consisting of thermoluminescence detector (TLDs) and CR-39 plastic nuclear track detectors (PNTD). The water shieldings were stored into the protective curtain at 4 layers, which is corresponding to the additional shielding thickness of about 8 g/cm2. The total mass of the protective curtain was to be 65 kg. That was installed along the outer wall of the starboard crew cabin in Russian Service Module. The dose reduction effect by water shielding was experimentally measured with the totally 12 passive dosimeter packages. Half of packages were located on the protective curtain surface and the other half packages were located on the crew cabin wall behind or aside the protective curtain. Two experiments for different duration were carried out onboard ISS crew cabin, 1) from July 4 to November 29, 2010 and 2) from December 17, 2010 to May 5, 2011. The dose reduction rate by the protective curtain was ranging from 15 to 70 % in absorbed dose due depending on the material thickness. We also tried to compare the results with the calculation based on Mote Carlo simulation. It is expected that the properly utilization of protective curtain would effectively reduce the radiation dose for crew living in space station. | |||||
