In clinical surgery it is impossible to organ dose, there are two methods used to obtain the organ dose: the computer simulation and direct measurement.
在临床手术中不能直接得到器官剂量，辐射剂量学中有两种方法用来得到器官剂量：计算机模拟法和直接测量法。
But he suggested that what could be obtained now are data about partial organ tolerance and dose constraints.
而他认为我们现在只能获得关于局部器官耐受性和剂量限制的数据。
In ICRP 1990 Recommendations, a new weighting factor——radiation weighting factorW_R was introduced to replace the quality factor Q for modifying the absorbed dose averaged over atissue or organ.
在国际放射防护委员会（ICRP）1990年新建议书中，引入了一个新的权重因数——辐射权重因数W_R，以取代原来使用的品质因数Q，用于对组织或器官中的平均吸收剂量按辐射品质进行加权。
The quantification of absolute activity in vivo is necessary procedure of estimating the absorbed dose of organ or tissue.
器官组织的绝对活度定量是吸收剂量估算的必要步骤。
