About Crew PADLES
>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.
How to carry a dosimeter while staying on orbit
>
>Japanese astronauts always carry Crew PADLES dosimeter through their flight between pre-launch to landing.
- During Launch and Landing
- The dosimeter will be put into a pocket of the Advanced Crew Escape Suit(ACES) for shuttle's crew members towards the ISS.
- During Intra-Vehicular Activities (IVA)
- The dosimeter is put into a chest pocket and or a belt bag of crew members.
- During Extra-Vehicular Activity (EVA)
- The dosimeter is put into a pocket located on the right/left leg of the Extravehicular Mobility Unit (EMU).
Flight Schedule of Crew PADLES
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.

International Collaboration - In-Flight Space Radiation Dose Measurements in Foreign Astronauts
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.
Malaysian Astronaut
Malaysian National Space Agency (Agensi Angkasa Negara : ANGKASA)
Born in 1972 in Kuala Lumpur, Malaysia, Doctor of Medicine.
He was selected as the first Malaysian astronaut in 2006.
He is the first Muslim who spent Ramadan (fasting month) in space.
ISS Flight: October 10 to 21, 2007 (Launched on Soyuz TMA-11(15S), and returned on Soyuz TMA-10(14S))
Korean Astronaut
Korea Aerospace Research Institute (KARI)
Born in 1978 in Gwangju, Korea, Doctor of Biological Engineering.
She was selected as the first Korean astronaut in 2006.
ISS Flight: April 8 to 19, 2008 (Launched on Soyuz TMA-12(16S), and returned on Soyuz TMA-11(15S))
