摘要

研制了组织等效比例计数器(TEPC)型空间辐射剂量计，用于现场航空辐射测量。它最初是作为低地球轨道上的小卫星的有效载荷而开发的。这个剂量计是基于TEPC的。它由a -150组织等效塑料外壳制成，内径6厘米，厚度0.3厘米。TEPC在13.9 torrs的温度下充满纯丙烷，以模拟直径为2 μm的电池。并实现了相关的便携式和低功耗电子器件。在仁川机场(ICN)和肯尼迪机场(JFK)之间的飞行过程中，通过地面标定实验和飞机高度的柳林观测进行了验证实验。通过与柳林观测的验证，发现TEPC剂量计可以作为航空高度空间辐射剂量计的监测仪器。

Preliminary Results of Tissue-Equivalent Proportional Counter (TEPC) Dosimeter for Measuring In-Situ Aviation Radiation

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.

期刊介绍： JASS aims for the promotion of global awareness and understanding of space science and related applications. Unlike other journals that focus either on space science or on space technologies, it intends to bridge the two communities of space science and technologies, by providing opportunities to exchange ideas and viewpoints in a single journal. Topics suitable for publication in JASS include researches in the following fields: space astronomy, solar physics, magnetospheric and ionospheric physics, cosmic ray, space weather, and planetary sciences; space instrumentation, satellite dynamics, geodesy, spacecraft control, and spacecraft navigation. However, the topics covered by JASS are not restricted to those mentioned above as the journal also encourages submission of research results in all other branches related to space science and technologies. Even though JASS was established on the heritage and achievements of the Korean space science community, it is now open to the worldwide community, while maintaining a high standard as a leading international journal. Hence, it solicits papers from the international community with a vision of global collaboration in the fields of space science and technologies.
