| 内容記述 | It is important to understand the behaviors of radionuclides in the agricultural systems since radionuclides enter humans through ingestion of foods. Critical staple foods are rice and wheat; the former is the dominant staple food crop in humid tropical and sub-tropical countries across the globe, and the latter is cultivated worldwide. Both are members of the Poaceae Family; however, they are different in cultivation methods. For example, rice is produced under flooded conditions but wheat is grown under upland field conditions. The difference in cultivation methods may affect plant uptake of radionuclides from soil. Thus we measured soil-to-grain transfer factors (TFs) of naturally existing elements as analogues of radionuclides for rice and wheat cultivated in Japan. For this work, we collected from 63 sites for rice and 7 sites for wheat; to the results of wheat, we added 2 barley samples since their cultivation methods were the same. The elements we measured for TFs were Li, N, Na, Mg, Al, Si, P, K, Ca, Sc, Ti, V, C, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Ag, Cd, Sn, Sb, I, Cs, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, W, Tl, Pb, Ra, Th and U. Geometric means of TFs of these elements were compared between rice and wheat grains; the tendency was almost the same and the correlation factor was more than 0.98 by Student's t-test (p<0.001). However, there were elements showing TF differences by a factor of 5 or more; that is, As, Ba and Ra. | |||||
