近地卫星舱内粒子计数率随空间位置的变化

Variation of Count Rate of Charged Particle in the Cabin with Space Position in Near Earth Orbit.

为测量近地轨道空间舱内辐射环境 ,在卫星内搭载了两台带有定时数据存储功能的盖革 -弥勒 (G -M)计数管式辐射测量仪 ,获得了卫星飞行期间 ( 1 5d)舱内带电粒子计数率动态变化的完整数据。通过分析 ,可获得此次飞行卫星舱内辐射环境随轨道空间位置变化的信息 ,能够较完整的描绘出南大西洋异常区辐射环境的粒子等剂量曲线。

Two Geiger-Mueller radiation dosimeters, equipped with data recorders, were placed in the recoverable satellite launched on Oct.20, 1996. The data recorder was used to record the count rate of proton acquired by the Geiger-Mueller dosimeter dynamically.From the obtained data, the area of high proton flux and the contour map of South Atlantic Abnormal was plotted.
