Abstract
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.
