“…From the data in Fig. 4 of Straume et al (2006) a pre-Chernobyl 129 I inventory can easily be derived which would be a factor of two higher that given by Straume et al (2006) and which would be in reasonable agreement with our estimate considering the uncertainties induced by the variability of different samples. For 137 Cs, the pre-Chernobyl inventories can also be calculated from data given in reports by UNSCEAR (1982UNSCEAR ( , 1993UNSCEAR ( , 2000.…”

“…For 137 Cs, the pre-Chernobyl inventories can also be calculated from data given in reports by UNSCEAR (1982UNSCEAR ( , 1993UNSCEAR ( , 2000. From these data one expects for a geographical latitude of 51 N a decay corrected 137 Cs fall-out for the 1980s between 4.6 kBq m À2 and 5.2 kBq m À2 , much closer to our estimates than to those by Mironov et al (1999Mironov et al ( , 2002 and Straume et al (2006). However, the preChernobyl fall-out of 137 Cs does not affect the conclusions regarding the fall-out due to the Chernobyl accident, the latter being much higher than the former.…”

a b s t r a c tThe radiation exposure of thyroid glands due to 131 I as a consequence of the Chernobyl accident was investigated retrospectively based on 129 I and 137 Cs inventories in soils in Northern Ukraine. To this end, soil samples from 60 settlements were investigated for 129 I, 127 I, and 137 Cs by AMS, ICP-MS and gammaspectrometry, respectively. Sampling was performed between 2004 und 2007.In those parts of Northern Ukraine investigated here the 129 I and 137 Cs inventories are well correlated, the variability of the individual 129 I/ 137 Cs ratios being, however, high. Both the 129 I and 137 Cs inventories in the individual 5 samples for each settlement allowed estimating the uncertainties of the inventories due to the variability of the radionuclide deposition and consequently of the retrospective dosimetry.Thyroid equivalent doses were calculated from the 129 I and the 137 Cs inventories using aggregated dose coefficients for 5-year old and 10-year-old children as well as for adults. The highest thyroid equivalent doses (calculated from 129 I inventories) were calculated for Wladimirowka with 30 Gy for 5-years-old children and 7 Gy for adults. In 35 settlements of contamination zone II the geometric mean of the thyroid equivalent doses was 2.0 Gy for 5-years-old children with a geometric standard deviation (GSD) of 3.0. For adults the geometric mean was 0.47 Gy also with a GSD of 3.0. In more than 25 settlements of contamination zone III the geometric means were 0.82 Gy for 5-years old children with a GSD of 1.8 and 0.21 Gy for adults (GSD 1.8).For 45 settlements, the results of the retrospective dosimetry could be compared with thyroid equivalent doses calculated using time-integrated 131 I activities of thyroids which were measured in 1986. Thus, a critical evaluation of the results was possible which demonstrated the general feasibility of the method, but also the associated uncertainties and limitations.

Dolon village, located about 60 km from the border of the Semipalatinsk nuclear test site, is known to be heavily contaminated by the first USSR atomic bomb test in August 1949. Soil samples around Dolon were taken in October 2005 in an attempt to evaluate internal thyroid dose arising from incorporation of radioiodine isotopes (mainly (131)I). Iodine-129 in soil was measured by using the technique of accelerator mass spectrometry. The (129)I/(127)I atom ratios measured were in the range from 3.3 x 10(-9) to 3.3 x 10(-7). These values were within the range of the current background level ( approximately 10(-9) to 10(-7)) in the environment, including contributions from the global fallout of atmospheric nuclear tests and local fallout of nuclear facilities. The (129)I atom accumulated level in soil ranged from 1.28 x 10(13) to 1.59 x 10(14) atoms m(-2), the average (8.0 x 10(13)) of which was higher than the background level of (2-5) x 10(13). From the relationship between (129)I and( 137)Cs (corrected for background and decay from 1949 to 2005) accumulated levels, the background level of (129)I and the (129)I/(137)Cs ratio around Dolon were estimated to be (6.4 +/- 0.4) x 10(13) atoms m(-2) and 0.25 +/- 0.16, respectively. This (129)I/(137)Cs ratio is almost similar to the fission yield ratio for (239)Pu fast fission (0.24).
