Calculation of internal dose from ingested soil-derived uranium in humans: Application of a new method

Abstract: The aim of the present study was to determine the internal dose in humans after the ingestion of soil highly contaminated with uranium. Therefore, an in vitro solubility assay was performed to estimate the bioaccessibility of uranium for two types of soil. Based on the results, the corresponding bioavailabilities were assessed by using a recently published method. Finally, these bioavailability data were used together with the biokinetic model of uranium to assess the internal doses for a hypothetical but real… Show more

“…The result of correlation for recent sediment in Kirkuk city (table 2) and (appendix1) are summarized in (table 1) The very high positive correlation between Uwith (Ta and K 2 O) byr value (0.904 and 0.896) respectively, then high positive correlation of Uwith (TiO 2 , Y and Nb) byr value (0.822, 0.793 and 0.753) respectively and The good correlation of U with Na 2 Owith value (0.673) (figure 2) because according to Goldschmidtthis elementsare found in one group (Lithophile elements)of classification elements (Goldschmidt, 1954) while the good correlation of Uwith (p and P 2 o 5 ) by value (0.74 and 0.68) respectively because one of the main sources of Uare from fertilizers that's have high values of phosphor (Träber et al, 2015). The good negative correlation of U with (Ni and Co) by value (-0.79 and -0.783) respectively because the source of this element is different with source of U in the environments.…”

“…There are three isotopes for U with percentages by mole fraction and half-lives of 234 U 0.0054% (245,500 Years), 235 U 0.72% (704,000,000 Years) and 238 U 99.27 % (4,468,000,000 Years) (Berglund and Wieser, 2011;Träber et al, 2015). This element has a very high density (18.95 g /cm 3 , 1.7 times higher than lead density of 11.35 g /cm 3 ).…”

“…The experiments were repeated for each types of soil. The solutions were stored frozen until measured with inductively coupled plasma mass spectrometer (ICP-MS) [14][11][15] [9]. Table 2 represents the measured chemicals and enzymes used for 0.5 g of soil [15].…”

“…Meanwhile study by Stanek and Calabrese [7] summarised the soil ingestion in the range of 0.013 -0.138 g/day for children and estimation of 0.01 g/day for adults [8]. Dose assessment conducted by Traber et al [9] in order to estimate the exposure risk for 238 U after soil ingestion, an intake of 0.01 g/day was assumed. Through deliberate or involuntary ingestion of soils, the chemical and biological components of soils can either be beneficial or detrimental to human health.…”
