The extensive efforts that ICRP has invested are acknowledged and praised in the preparation of this document. Upon reviewing the draft, a few points are listed below that will aid in clarification and accessibility of the publication.
Comments on ICRP-Dose coefficients for Intakes of Radionuclides by Members of the Public: Part 1
Line 1725 “For decay chains whose members are all isotopes of the same element, the progeny is assigned the same kinetics as the parent throughout the body.” Please add an example to clarify. Is it referring to Figure A.# series for uranium/thorium decay chain series?
Line 1831 equation 2.6 - what is the use of the equation? Explanation of why error correction is necessary.
Line 1847 Dose calculation time period:
Is the age of the adult age specific or 50 years
For bone seekers radionuclides, is the adult age changed from 20 to 25 years old?
Line 436 Phantom today has over 40 target tissues (ICRP 133) while tissue weighting refers to 20. Should the rest of the target tissue be ignored in calculating effective dose?
Line 436 table 1.3; Gonads – should add a comment on sex specificity to match the notation for sex specific remainders.
Table A.1 has both AMTD and AMAD as the defining variable for the rows, good to see that the table series has a break between the different diameter types as it avoids confusion.
Repeated variable names is confusing for fa and fr
Line 3800 Table 15.2 - use of abbreviations in the table- cort bone trab bone are not clear and were not defined before.
Line 3800 Table 15.2 table is missing alimentary track transfer coefficients – from right colon to feces – is not clear where those coefficients should be taken from.
Line 4971 Table 26.3 - in the schematic model (fig 26.2) Plasma and RBC are defined as compartments. However, in table 26.3 they are not used, instead (presume) blood compartment is used. This is unclear if blood is plasma or RBC or both.
Line 4971 Table 26.3- in the schematic model (fig 26.2) Sweat is defined as compartment. However, in Table 26.3 it is not used, instead (presume) Excreta compartment is used. That is also unclear.
