Human Respiratory Tract Model for Radiological Protection. This report describes a revision of the model used in ICRP Publication 30 to calculate radiation doses to the respiratory tract of workers resulting from the intake of airborne radionuclides. This revision was motivated by the availability of increased knowledge of the anatomy and International Commission on Radiological Protection (ICRP) has developed several biokinetic models over the years to describe the transfer of activity throughout the body and through routes of excretion. Some of the models most often used are described in ICRP Publications 23 (ICRP 1975), 30 (ICRP 1979), 56 (ICRP 1989), 66 (ICRP 1994), View ICRP 66 The Human Respiratory Tract Model, Ann.

The chronic model for 239,240 Pu shows that calculated/measured ratios for pulmonary lung are 0.95 and 1.3 for ICRP 30 and ICRP 66, respectively. The ratio for the bronchial tree is not possible because 239,240 Pu could not be detected in the tissue samples. However, the ICRP 66 calculation for the tree was large, i.e. 10 % of the pulmonary value.

This revision was motivated by the availability of increased knowledge of the the ICRP 30 model. Likewise under the ICRP 66 model, the lung is cleared quickly, however, it continues to accumulate dose due to the incorporation of additional material from recycling. The ovcrall affect is that the 50 year committed lung dose associated with the ICRP 66 model is 25% higher than the ICRP 30 model. 1 ICRP-2 was mentioned in the body of the Commission paper but not included in this comparison because it was fundamentally diffe rent than the other reports. The external limit for occupational workers was 5(N-18) rem, where N=the worker's age. The internal dose was driven by the organ dose, Lung model (ICRP 66)Lung model (ICRP 66) - regions • Can be applied for workers and the public for inhalation of particles, gases and vapours • "Reference worker" = a male breathing normallymale breathing normally through the nose while performing light workperforming light work. ERRATA FOR ICRP PUBLICATION 66 The following information was in error in Publication 66 (Annals of the ZCRP, 24, l-3): Page 35, Table 10, Page 105, Table 24, and Page Multiplying 42.9 mg. by 1.75 gives: 75 mg. Similarly, using ICRP 66, 21 mg corresponds to an intake of 75 mg. (21/0.28 = 75) Summary: NUREG-1 391 uses 21 mg as the threshold for permanent kidney damage. Under the old ICRP 30, the NRC calculated that an intake of 40 mg of soluble uranium would cause a systemic burden of 21 mg.
