在我国１９９６年的返回式卫星舱内，搭载了２台Ｇ－Ｍ计数管型辐射测量仪，取得了卫星飞行期间（１５ｄ）舱内带电粒子计数率动态变化的数据。每台仪器的４万多个计数率数据中，８０％以上的计数率小于１５０／ｍｉｎ，大于５００／ｍｉｎ的仅占２％以下，最大计数率达６×１０３／ｍｉｎ。计数率随飞行时间呈周期性变化，周期约为４５ｍｉｎ，除每日出现４～５组大计数率数据外，一般的变化幅度是０～２００／ｍｉｎ。南大西洋异常区是引起计数率增大的原因。卫星上的热释光剂量计测出飞行１５ｄ的舱内平均日剂量为０．１７９ｍＧｙ／ｄ。
In our country’s return type satellite capsule in 1996, we carried two G-M counter tube type radiation measuring instruments and obtained the data of the dynamic change of the counting rate of charged particles in the satellite flight (15d). More than 40,000 count rate data of each instrument, more than 80% of the count rate is less than 150 / min, more than 500 / min only less than 2%, the maximum count rate of 6 × 103 / min. The counting rate varies cyclically with flight time, with a period of about 45 minutes. Except for 4 to 5 sets of big counting rate data daily, the general variation range is 0-200 / min. The anomalous area of the South Atlantic is the cause of the increase in the count rate. On the satellite thermoluminescence dosimeter measured 15d flight cabin average daily dose of 0.179mGy / d.
