| 英文摘要 | In the present study, i-129 activities and i-129/i-127 atom ratios were measured in 60 soil samples contaminated by the fukushima daiichi nuclear power plant (fdnpp) accident. the i-127 concentrations, i-129 activities, and i-129/i-127 atom ratios in dry-weight were observed to be 0.121-23.6 mg kg(-1), 0.962-275 mbq kg(-1), and (0.215-79.3) x 10(-7), respectively. the maximum values of both i-129 activities and i-129/i-127 atom ratios in japanese soil increased about three orders of magnitude due to this accident. the equation logy = 0.877logx + 0.173 (pearson's r = 0.936; x, i-129 concentration; y, i-131 concentration; decay-corrected to march 11, 2011) instead of a simple constant may be a better way to express the relationship between i-129 and i-131 in japanese soil affected by both global fallout and fdnpp accident fallout. in addition, a moderate correlation was observed between i-129 and cs-135 (logy = 0.624logx + 1.01, pearson's r = 0.627; x, i-129 activity; y, cs-135 activity). however, i-129 presented larger fractionations with less volatile radionuclides, such as u-236, pu-239, and pu-240. these findings indicated cs-135 could be roughly estimated from i-129 or i-131; this is advantageous as fewer cs-135 data are available and cs-135/cs-137 is being considered a promising tracer during radiocesium source identification. |
