摘要
用蒙特卡罗和解析计算相结合的方法,计算研究了一种就地HPGeγ谱仪对土壤中的天然和人工放射性核素的响应问题,考虑实地测量中车辆的影响和土壤中核素的不同分布,得出了谱仪的全能峰计数率与土壤中不同核素比活度间的关系(即校准系数)。
This paper reports the study of calibration coefficients for a in-situ HPGeγspectrometer. The spectrometer response for γ rays emitting from radioactive nuclides in soil was calculated by Monte Carlo methods. Considering different distributions of each nuclide in soil and the influence of vehicle, we obtained the relationship between the count rates of full-energy-peak on spectrometer and the activity of nuclides.
