英文摘要 | Kinetics of Cs-137, Co-60 and Sr-85 sorption on powdered building materials in aqueous suspensions at 20 degrees C for interaction times of 1, 7, 14 and 28 days were studied. The Cs-137 distribution coefficient (K-d) values for all building materials except limestone practically did not change during 28 days of sorption. The K-d ((85)sr) was several orders of magnitude lower than for Co-60. The highest values were observed for asphalt and granite. An effective method to study the radionuclide distribution in depth of building materials using layer-by-layer sanding was developed. Using the developed method, the Cs-137, Co-80 and Sr-85 distribution with depth of selected building materials at different air humidity, time and temperature was studied. Relative humidity (RH) was found to influence significantly the Sr-85 depth distribution in the case of granite (unlike Cs-137 and Co-60). While Sr-85 penetrated to 0.5 mm in depth of granite at RH 30%, at RH 87% the depth of Sr-85 penetration to granite reached up to 7 mm. (C) 2013 Elsevier Ltd. All rights reserved. |
