Outline of Final Research Achievements |
We developed accelerator mass spectrometry of anthropogenic long-lived radionuclides such as C-14, Cl-36, I-129 and others for environmental impact assessment. Radioiodine is one of the most important radionuclides released from the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. We have clearly articulated the environmental fate of radioiodines on terrestrial environment. After the FDNPP accident, the average isotopic ratio of I-129/I-131 is estimated to 26.0 ± 5.7 as at March 11, 2011. On the basis of these results, we developed the rare-particle detection system to be able to measure environmental levels of long-lived radionuclides at the University of Tsukuba.
