(接上期)(3)有定向当量剂量信息:(1)通用计算方法。当有与器官剂量计算相应的X、γ辐射场的定向剂量当量率的信息,应用公式10估算空气比释动能率(k),再用公式2估算器官剂量。k=H(0.07)/C_(KH),(10)式中:H(0.07)—X、γ辐射场的定向剂量当量率,Sv/h;C_(KH),—空气比释动能到定向剂量当量的转换系数,Gy/Sv,其值见表6。(2)核事故早期烟羽情况。这时应先估算定向
(Continued) (3) There is directional equivalent dose information: (1) general method of calculation. When there is information on the directional dose equivalency of the X, γ radiation field corresponding to the organ dose calculation, Equation 10 is used to estimate the air kerma rate (k), and then Equation 2 is used to estimate the organ dose. (10) where: H (0.07) -X, directional dose equivalent rate of γ radiation field, Sv / h; C_ (KH), - air kerma can be directed to The conversion factor of dose equivalent, Gy / Sv, is given in Table 6. (2) The situation of plume early in nuclear accident. At this time should first estimate the orientation
