宇宙射线是人类所受天然辐射照射的重要组成部分。宇宙射线电离量是指宇宙射线中的电离成分在单位体积自由空气中的离子产生率,常用单位为I(标准状况下每立方厘米自由空气中每秒产生一个离子对),1I相应的空气吸收剂量率为1.50 × 10~(-8)Gy·h~(-1)。为了估算全民所受天然辐射剂量,我们从1980年至1987年在全国范围30个不同纬度和海拔高度的水面上和一次高空气球实验中测量了宇宙射线电离的分布。测量
Cosmic rays are an important part of natural radiation exposure to human beings. The cosmic ray ionization refers to the ionization rate of ionizing components in cosmic rays per unit volume of free air. The common unit is I (one ion per second per cubic centimeter of free air in standard condition), and the corresponding air absorption of 1I The dose rate was 1.50 × 10 ~ (-8) Gy · h ~ (-1). In order to estimate the natural radiation dose received by the whole population, we measured the ionization distribution of cosmic rays from 1980 to 1987 at an experiment on 30 water surfaces at different latitudes and altitudes across the country and in a high-altitude balloon experiment. measuring
