高纯锗γ谱仪对放射性标准土壤的探测效率刻度

Detection Efficiency Calibration of Radioactive Standard Soil Matter With HPGe Detector

摘要: 通过测量放在样品盒内压实后8个不同高度的土壤标准物质，得到HGPe γ 谱仪的γ射线能量-效率曲线，并用蒙特卡罗程序MCNP进行相应计算，结果表明，实际测量值与蒙特卡罗方法计算值符合得较好。

Abstract: Eight radioactive standard soil matters with different impacted height were measured by HGPe detector, and eight efficiency curves were obtained. The calibrated curves were testified by Monte-Carlo Program MCNP, and they they agree each other.
