^（60）Coγ辐照装置增源后剂量测定

DOSE RATE MEASUREMENT BEFORE COMMISSIONING OF ￣(60)Co γ-IRRADIATION EQUIPMENT

在增源１．２２ｐＢｑ６０Ｃｏγ辐照装置启用前，准确测量了源到辐照位置重复性和辐射场空间剂量率，以及产品箱中吸收剂量的不均匀度。对岛津ＵＶ－２２０１紫外分光光度计进行了校准并测定了该仪器摩尔消光系数。在实验条件下使硫酸亚铁剂量计标准化，剂量测试结果与国家计量院比对具有较好的一致性。

Accurate measurement cobalt source irradiation position repeatablity.dose rate at irradiation field and the dose uniformity ratio of product in the boxes before commissioning of supplement 1.22 pBq 60Co γ-irradiation plant. Under the experiment conditions we made the ferrous sulphate dosimeter standardization, a good dose reappear compare with measurement of National Dose Reasearch institute.
