文摘

Aerosols from the Fukushima Dai-ichi Nuclear Power Plant accident were collected at the Geological Survey of Japan. The temporal patterns of the 134Cs/137Cs, 136Cs/137Cs, and 132Te/137Cs activity ratios were consistent with expectations based on their half-lives. Those for 131I and 129mTe decreased with some fluctuations. 110mAg/137Cs declined more rapidly than expected and 95Nb/137Cs increased with time. The results suggest that the temporal patterns depended not only on their half-lives but also on many factors such as chemical speciation, the diversity of sources, changes in the temperature and discharge rate from the reactors, and the processes of transport.
