Description

Iodine-129 (129I) concentration in several water samples collected around Fukushima area were measured by means of Accelerator Mass Spectrometry. The results were discussed in relation with Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. 129I concentration of river waters collected Iitate village and Minami-Soma city (North to North-west of FDNPP) showed as high as 1.0x109 atoms/L and had not vary significantly during period from March to October, 2012. The combination of 129I/127I ratio and 127I concentration of these water samples can be explained as mixture of fossil rain water (ground water) and the rain radioactively contaminated by FDNPP accident. Considering the accident origin 129I deposition in Northwest of FDNPP (∼1.4x1014 atoms/m2) and annual precipitation rate (∼1360 mm, Iitate village), it is figured out that only about 0.3% of total inventory is transported by the river system annually.
