| Summary: | We develop the tissue-equivalent proportional counter (TEPC) type’s space radiation dosimeter to measure in-situ aviation
radiation. That was originally developed as a payload of small satellite in the low-earth orbit. This dosimeter is based on a
TEPC. It is made of an A-150 tissue-equivalent plastic shell of an internal diameter of 6 cm and a thickness of 0.3 cm. TEPC
is filled with pure propane at 13.9 torrs to simulate a cell diameter of 2 μm. And the associated portable and low power
electronics are also implemented. The verification experiments have been performed by the calibration experiments at ground
level and compared with Liulin observation at aircraft altitude during the flight between Incheon airport (ICN) and John F.
Kennedy airport (JFK). We found that the TEPC dosimeter can be used as a monitor for space radiation dosimeter at aviation
altitude based on the verification with Liulin observation. |
