Crew PADLES is used to verify personal radiation exposure for the Japanese astronauts during their stay onboard the ISS. Career dose limits in space can be determined considering astronaut's personal dosimetry against dose limit set for astronaut health protection.
Crew PADLES dosimeter is a passive and integrating type of the dosimeter. It is contained in a small polycarbonate case, the frame has a strap hole to tie a JAXA strap, so that it is easy to wear it for Japanese astronauts during their EVA/IVA activities.
Japanese astronauts always carry Crew PADLES dosimeter through their flight between pre-launch to landing.
Up to now, the following astronauts brought Crew PADLES dosimeters to the Space Shuttle/ISS with them for personal dosimetery. Those Crew PADLES dosimeters were brought back to the ground with the astronauts and processed for data analysis at JAXA Tsukuba Space Center.
The following two foreign astronauts have used Crew PADLES dosimeters during their flight on the ISS for radiation dose measurements. These were conducted part of the international collaborative activities using the Crew PADLES.
