目前,国际上已普遍采用H*(10)、Hp(10)、H′(0.07)三个实用量作为剂量限值控制的评价依据,因此辐射剂量监测仪器也应按这些量进行校准。在标准实验室通常只测定X、γ射线空气比释动能、β射线组织吸收剂量等基本量,再乘以国际标准推荐的转换系数得到所需实用量的约定真值,此时不考虑转换系数的不确定度。然而,新研究结果显示:由于各种干扰因素的存在,对于国际标准ISO4037-1中给出的标称相同的辐射质,不同实验室通过能谱测量得到的转换系数的合成标准不确定度
At present, the international practical application of H * (10), Hp (10), H ’(0.07) as the basis for the dose limit control assessment, radiation dose monitoring instruments should also be calibrated in these quantities. In the standard laboratory, only X, γ-ray air kerma, β-ray absorbed dose and other basic parameters, and then multiplied by the international standard conversion factor to obtain the required practical value of the actual value, this time without considering the conversion factor The uncertainty. However, the results of the new study show that the synthetic standard uncertainty of the conversion factors obtained by spectroscopy measurements by different laboratories for the nominally identical radiators given in the International Standard ISO 4037-1, due to various disturbing factors
