[General comments] The draft does not discuss well about the uncertainties related with vertical distribution of radionuclides in soil. It is recommended to add following sentences on line 552 (or another appropriate place). “…. many of these factors. Concentrations of Radionuclides (e.g. radiocesium) in forest soil change with depth even after long time from deposition. A few cm of topsoil often has orders of magnitude higher concentration than deeper layers. Therefore, CR value for terrestrial RAPs especially pine tree strongly depend on the soil depth considered for calculation, and aggregated transfer factors based on the deposition are often used to solve this problem. In this report, if transfer data were related to radionuclide deposition, the values were converted to activities in soil with 10 cm sampling depth as described in paragraph (65). With respect to …” In chapter 2, line 533, the report start using fresh weight base CRs without any notice on the possible use of dry or ash weight bases ones. It is better to add following sentence at the beginning of paragraph (38). “There are several definitions of concentration ratio (CR). In this report, the fresh weight (fw) activity concentrations of …..” In line 658 and later: the term “baseline transfer parameters” was used without any definition. Reader needs explanation on the meaning of “baseline”. In paragraph (81), homeostatic control of elemental concentration was discussed. However, there is no further discussion whether CRs are useful for such elements or not. It is better to add following sentence, if the report does not calculate CRs for elements controlled homeostatically. “… is effectively constant (e.g. Koulikov and Meili 2003). In such case, CR values are not applicable.” In addition, tables for CR values should be consistent with this statement. For example, data for K is better to be removed or be shown with annotation. Values in tables should be checked considering following points. line 1614: "Geometric mean" of Po is lower than "Minimum" value of Po line 1629: "Geometric mean" of Am is lower than "Minimum" value of Am line 1641: Please check ID334 and ID344. If the same reference, re-calculate "Arithmetic Mean", "Arithmetic Standard Deviation", "Geometric Mean", "Geometric Standard Deviation" of Ni, Pb, Ra, Th and U. line 1674: "Geometric mean" of Cs is lower than "Minimum" value of Cs line 1674: 17 samples of U can have "Std= 0"? line 1679: "Geometric mean" of Cs is lower than "Minimum" value of Cs line 1686: "Arithmetic Mean" and "Geometric mean" of Am are lower than "Minimum value" of Am.
