| 内容記述 | In the decommissioning field of the Fukushima Daiichi Nuclear Power Plant, several kinds of radionuclide-contaminated demolition debris are discharged. Although demolition debris contaminated with uranium at high concentrations has not yet been detected, it may be encountered in the near future. Since uranium radioisotopes rarely emit easily detectable α- and γ-rays, quantification of uranium in the demolition debris by radiation measurement is difficult. The most suitable method for this purpose is mass analysis of an acid elution solution of the demolition debris by inductively coupled plasma mass spectrometry (ICP-MS). Total reflection X-ray fluorescence (TXRF) analysis is another potential technique to estimate uranium in an acid elution solution of demolition debris. Although ICP-MS has higher detection sensitivity than TXRF analysis, it requires a time-consuming ashing process for decomposition of the organic matter which is not required for TXRF analysis. In this paper, we demonstrate that the viability of using TXRF analysis as a screening method for uranium-contaminated concrete. Uranium was extracted from a model acid elution solution of uranium-contaminated concrete by using chromatography resin separation. The uranium content in the model solution obtained by TXRF measurement was similar to that obtained by ICP-MS measurement. Although the obtained minimum detection limit of uranium for TXR measurement, 1.4 ng/mL, is higher than that for ICP-MS, 0.002 ng/mL (U-238), the total analysis time for TXRF measurement, about 6 hours, is one third of that for ICP-MS. | |||||
