作者前曾参照国际放射防护委员会第３０号出版物（ＩＣＲＰ－３０）给出了摄入混合裂变产物后内照射剂量的简便估算方法。现根据ＩＣＲＰ１９９４年人类呼吸道模型，重新给出了这一估算方法。计算出衰变速率系数ｎ＝０．２～２．０时呼吸道与消化道靶组织所受的待积当量剂量及其所致的待积有效剂量。用１９９４年呼吸道模型计算的结果低于１９７９年新肺模型的所得结果。
In the light of ICRP Publication No. 30 (ICRP-30), the author previously gave a simple estimate of the internal dose after ingestion of mixed fission products. Now based on the ICRP1994 year classification model, this estimate is given again. Calculated when the decay rate coefficient of n = 0.2 ~ 2.0 respiratory tract and gastrointestinal target tissue to be plot equivalent dose and its product to be plot effective dose. Results obtained with the 1994 respiratory model were lower than those obtained with the new lung model of 1979.
