内容記述 | For estimation of radiation doses to organisms, concentration ratios (CRs) of radionuclides are required. In the present study, CRs of various elements were obtained as analogues of radionuclides for algae, molluscs, and crustaceans, in eight estuarine areas around Japan. The elements measured were Na, Mg, K, Ca, V, Mn, Fe, Co, Ni, Cu, Rb, Sr, Y, Mo, Cd, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Pb, and U. The geometric mean (GM) values of CRs (GM-CRs) for alkali and alkaline earth elements, Mo, and U for all biota, as well as V for crustaceans, were less than 100 L/kg, while GM-CRs for the other elements were higher. When the obtained GM-CRs were compared with the CRs recommended in IAEA Technical Report Series 422 for marine organisms, no big differences between them were found; however, the GM-CRs of several elements (i.e., Cd and U for algae, Mn for molluscs, and Pb for crustaceans) were lower than the recommended CRs. In the present study, conversion factors (the ratio of CR for the whole body to that for muscle) for molluscs and crustaceans were also calculated, since data on edible parts of these organisms are generally available in the literature. For crustaceans, GM-conversion factors of all the elements were more than one. For molluscs, GM-conversion factors of rare earth elements and U were slightly higher than those for crustaceans, while GM-conversion factors of the other elements were almost the same and less than 10. These results indicate that some elements are tended to be concentrated in internal organs of biota collected in the estuarine areas. For the evaluation of CR data on whole body for radiological assessment, conversion factor could be useful parameter. | |||||
