能谱-剂量转换法用于环境辐射剂量测量

为准确测量环境水平剂量率，基于无卷积全谱转换法，通过测量X/γ能谱和剂量率，开展能谱-剂量转换系数求解并实现能谱-剂量的转换。结果表明，能谱-剂量法计算剂量率与实测剂量率的残差近似为0，证明该方法在能谱-剂量求解过程自洽；在¹³⁷Cs、⁶⁰Co标准参考辐射场下的剂量率线性测试结果与标准值的最大相对误差为±10%，表明无卷积全谱转换法用于能谱-剂量转换系数的求解可行。

Energy Spectrum to Dose Conversion Method Used in Environmental Radiation Dose Measurement

In order to accurately measure the environmental level dose rate, based on the G(E) function method and conversion of complete spectra without deconvolution method, the energy spectrum and dose rate of X/γ ray was measured for calculating spectrum-dose conversion coefficient. And finally the conversion of energy spectrum to dose rate is realized. The residual difference between the calculated dose rate by the energy spectrum-dose method and the measured dose rate value is approximately 0, which proves that the method is self-consistent. Experiments have been conducted in ¹³⁷Cs and ⁶⁰Co radiation fields, and the maximum relative error of dose rate is ±10%, which proves that the G(E) function method and Conversion of complete spectra without deconvolution method are feasible for energy spectrum-dose conversion.
