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. |
