摘　　要：铀矿尘所致人体内照射剂量估算时需要的参数较多,计算过程繁琐。采用剂量系数法对铀矿尘所致内照射剂量进行估算,可将复杂的模型计算简化,同时也能较好地反映出铀矿尘所致内照射的剂量水平。通过对铀矿尘粒径和铀矿石核素化合物形态等因素的研究,确定估算时应选取的剂量转换因子和所选取铀矿尘的类型,从而提出铀矿尘所致人体内照射剂量估算方法。Many parameters were needed when we carried out internal individual radiation dose estimation with the uranium dust, and the calculation was very troublesome. In this study, the dose coefficient method was used to estimate internal radiation dose caused by uranium dust. The method can simplify the complicated model calculation, at the same time it could reflect the internal radiation dose level caused by uranium dust better. Through the research including uranium dust AMAD and uranium ore nuclide compound form and other factors, we determined the dose conversion factor and the type of uranium dust that we should selected in the estimation, and then put forward a new method of internal individual radiation dose estimation caused by the uranium dust.
