| 内容記述 | Uranium (U) concentrations in crop samples are usually low, making it difficult to obtain soil-to-plant transfer factors (TFs) under agricultural field conditions. In this study, U concentrations in rice and associated soil samples have been determined by inductively coupled plasma mass spectrometry (ICP-MS) after chemical separation with TRU resin (Eichrom). After U extraction on the resin by sample solution loading, tetramethyl ammonium hydroxide was studied for U elution behavior from the resin cartridges. Chemical recovery with this method was about 85%. Then U concentrations in three kinds of rice grain samples, brown rice (hulled rice), white rice (polished rice) and bran (63 samples each), were measured by ICP-MS after the TRU resin extraction method. U concentrations in all samples were measured and the geometric means in white rice, brown rice and bran samples were 7.3 x 10-5, 9.7 x 10-5 and 3.7 x 10-4 mg/kg-dry, respectively. TFs for white rice ranged from 6.2 x 10-6 to 7.9 x 10-5 with a geometric means of 2.7 x 10-5, whereas those for brown rice ranged from 5.5 x 10-6 to 4.6 x 10-4 with a geometric means of 3.6 x 10-5. These values were 2 orders of magnitude lower than the TF for cereals of 1.3 x 10-3 proposed by IAEA. | |||||
