摘要
本文测定了3台闪烁型γ外照射剂量仪(国产FT-620和SG-102)对宇宙射线响应值随海拔高度的变化。结果表明,3台外照射剂量仪对宇宙射线响应值随海拔高度(365—1910m)的变化趋势与高压电离室基本相同,即各台仪器对宇宙射线的相对灵敏度(以高压电离室的归一)随海拔高度变化不大(最大相对偏差不大于18%);但各台仪器对宇宙射线的相对灵敏度有较明显的差别。
The sensitivities of three scintillation-type γ dosimeters(Home made, Model FT-620 and SG-102(to cosmie rays were investigatedat different altitudes above sea level.The results suggested that thevariation of the response of three external dosimeter to cosmic rays withthe altitude is similar to that of the pressurized ion chamber,there wereon noticeable sensitivity changes to be observed for a same dosimeter atdifferent altitudes.However,it differed apparently among individualdosimeters.
