已经提出了两种计算人体剩余活动辐射剂量的方法。需要对累积的活动进行校正，使其反映出均匀分布在全身的活动。另一种方法需要校正S值，以便从身体的其余部分获得目标器官的S值。这两种方法的结果是一样的。我们已经研究了这些方法和在每种情况下计算辐射剂量所需的步骤。我们的结果表明，校正累积活性的方法是首选的，特别是如果源和靶器官的数量很大，并且没有配备必要软件的计算机。
Two methods for calculating the radiation dose from remaining body activity have been suggested. One requires correction of the cumulated activities so that they reflect the activity uniformly distributed in the total body. The other method requires correction of the S values so that a value of S for the target organ from the remainder of the body is obtained. These two methods give the same answer. We have examined these methods and the number of steps required to calculate the radiation dose in each case. Our results show that the method of correcting the cumulated activities is preferred, especially if the number of source and target organs is large and a computer equipped with the necessary software is not available.
