The applicability of a high-pressure xenon based spectrometer for determining the parameters of radioactive contamination of soil or building structures by ¹³⁷Cs resulting from a radiation accident was studied. For soil contaminated by ¹³⁷Cs with an exponential depth distribution, the Monte Carlo method was used to calculate the characteristics of the radiation field at the detection height and the instrumental gamma spectra. It is shown that there is promise in using such a detector to determine the parameters of the contamination penetration into the interior volume of the material. It is shown that the sensitivity of the measurement of activity along depth depends on the width of the working zone in the valley and the influence of the thickness of the body of the detector is determined.

研究了高压氙气光谱仪在确定由辐射事故引起的¹³⁷ Cs引起的土壤或建筑结构放射性污染参数方面的适用性。对于被¹³⁷污染的土壤对于具有指数深度分布的Cs，使用蒙特卡洛方法来计算检测高度和仪器伽马光谱的辐射场特征。结果表明，使用这种检测器来确定污染物渗透到材料内部空间的参数是有希望的。结果表明，沿深度进行活动测量的灵敏度取决于山谷中工作区的宽度，并确定了探测器主体厚度的影响。
