“…The half-life of 132 Te is 3.2 days and its decay product is radioactive 132 I, which is thyroid tropic. A previous study reported that radioactive tellurium that is orally administered to cows concentrates in the thyroid more than in most other tissues [19]. These results suggest that we need to pay more attention to 132 Te as well as 131 I in assessing health risk to the thyroid.…”

The Fukushima Daiichi Nuclear Power Plant (FNPP) accident released large amounts of radioactive substances into the environment. In order to provide basic information for biokinetics of radionuclides and for dose assessment of internal exposure brought by the FNPP accident, we determined the activity concentration of radionuclides in the organs of 79 cattle within a 20-km radius around the FNPP. In all the specimens examined, deposition of Cesium-134 (134Cs, half-life: 2.065 y) and 137Cs (30.07 y) was observed. Furthermore, organ-specific deposition of radionuclides with relatively short half-lives was detected, such as silver-110m (110mAg, 249.8 d) in the liver and tellurium-129m (129mTe, 33.6 d) in the kidney. Regression analysis showed a linear correlation between the radiocesium activity concentration in whole peripheral blood (PB) and that in each organ. The resulting slopes were organ dependent with the maximum value of 21.3 being obtained for skeletal muscles (R2 = 0.83, standard error (SE) = 0.76). Thus, the activity concentration of 134 Cs and 137Cs in an organ can be estimated from that in PB. The level of radioactive cesium in the organs of fetus and infants were 1.19-fold (R2 = 0.62, SE = 0.12), and 1.51-fold (R2 = 0.70, SE = 0.09) higher than that of the corresponding maternal organ, respectively. Furthermore, radiocesium activity concentration in organs was found to be dependent on the feeding conditions and the geographic location of the cattle. This study is the first to reveal the detailed systemic distribution of radionuclides in cattle attributed to the FNPP accident.

“…In a review by Hamilton (1948), the f 1 for tellurium was reported to be about 0.25 in rats. Mullen and Stanly (1974) reported that 0.25 of tellurate fraction was absorbed from the alimentary tract of dairy cows. The ICRP (1979) adopted an f 1 value of 0.2 for acute intakes by workers and 0.3 for chronic intakes by the general public (ICRP 1993 and 1996).…”

ALIMENTARY TRACT ABSORPTION (f 1 VALUES) FOR RADIONUCLIDES IN LOCAL AND REGIONAL FALLOUT FROM NUCLEAR TESTS

et al. 2010

This paper presents gastrointestinal absorption fractions (f 1 values) for estimating internal doses from local and regional fallout radionuclides due to nuclear tests. The choice of f 1 values are based on specific circumstances of weapons test conditions and a review of reported f 1 values for elements in different physical and chemical states. Special attention is given to fallout from nuclear tests conducted at the Marshall Islands. We make a distinction between the f 1 values for intakes of radioactive materials immediately after deposition (acute intakes) and intakes that occur in the course of months and years after deposition, following incorporation into terrestrial and aquatic foodstuffs (chronic intakes). Multiple f 1 values for different circumstances where persons are exposed to radioactive fallout (e.g. local vs. regional fallout and coral vs. continental tests) are presented when supportive information is available. In some cases, our selected f 1 values are similar to those adopted by the ICRP (e.g. iodine and most actinides). However, f 1 values for cesium and strontium derived from urine bioassay data of the Marshallese population are notably lower than the generic f 1 values recommended by ICRP, particularly for acute intakes from local fallout (0.4 and 0.05 for Cs and Sr, respectively. The f 1 values presented here form the first complete set of values relevant to realistic dose assessments for exposure to local or regional radioactive fallout.
