Can ¹²⁹I track ¹³⁵Cs, ²³⁶U, ²³⁹Pu, and ²⁴⁰Pu apart from ¹³¹I in soil samples from Fukushima Prefecture, Japan?

ABSTRACT: In the present study, ¹²⁹I activities and ¹²⁹I/¹²⁷I atom ratios were measured in 60 soil samples contaminated by the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. The ¹²⁷I concentrations, ¹²⁹I activities, and ¹²⁹I/¹²⁷I 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) × 10^-7, respectively. The maximum values of both ¹²⁹I activities and ¹²⁹I/¹²⁷I 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, ¹²⁹I concentration; y, ¹³¹I concentration; decay-corrected to March
