基于相对误差分段的剂量率拟合转换方法

针对计数与剂量率数据拟合过程中低剂量率误差偏大问题，提出一种基于相对误差分段的剂量率拟合方法。以相对误差为判断依据，依次从高剂量率区域往低剂量率区域开展剂量率数值拟合，使拟合剂量率值中，高剂量率段相对误差均非常贴近于真值，同时低剂量率区域通过分段方式亦贴近于真值。结果表明，该剂量率拟合转换方法结果更贴近真值。

Dose Rate Fitting Conversion Method Based on Relative Error Segmentation

A dose rate fitting method based on relative error segmentation is proposed to solve the problem of low dose rate error in the process of counting and dose rate data fitting. Taking the relative error as the judgment basis, the dose rate value fitting is carried out from the high dose rate area to the low dose rate area in turn, so that the relative error of the high dose rate section in the fitted dose rate value is very close to the true value, and the low dose rate area is also close to the true value in a subsection mode. The results show that the dose rate fitting conversion method is closer to the true value.
