摘要

本研究利用数学模拟方法，获得了将装有碘化镓（31 × 31 毫米）探测器的机载伽马射线光谱仪的脉冲高度谱转换成剂量率值的数据。在 15 米至 75 米的高度上，使用模型任务对确定脉冲高度谱的结果进行了测试。60Co 的各向同性点源和土壤表面 137Cs 的无限污染被视为伽马辐射源。模拟采用蒙特卡罗方法进行。因此，评估了剂量率估算转换系数的不确定性。

Determination of the dose rate from the pulse-height spectra of an airborne gamma-ray spectrometer based on an unmanned aerial vehicle

In the present study, data for converting the pulse-height spectra of an airborne gamma-ray spectrometer with a NaI (31 × 31 mm) detector to the dose rate values were obtained using the mathematical simulation. The results were tested using model tasks for determining pulse-height spectra at heights from 15 to 75 m. A point isotropic source of ⁶⁰Co and the infinite contamination of the soil surface with ¹³⁷Cs were considered as sources of gamma-radiation. The simulation was carried out using the Monte Carlo method. As a result, uncertainties of obtained conversion coefficients for dose rate estimations were evaluated.
