Abstract

Five years have passed since the Fukushima nuclear accident. Immediately after the accident, 40 to 50 academic staff members of Agricultural Dept. of The University of Tokyo started to study the movement of radioactive materials emitted from the nuclear reactor, since most of the contaminated area in Fukushima is related to agriculture. They are still continuing their research to find out the effects of the accident in agricultural fields. Our Graduate School holds many research fields, and there are many facilities attached to the School, such as meadows, experimental forests, farming fields, etc. Together with these facilities a lot of on-site studies have been conducted in Fukushima. One of the most important findings was that the fallout was found at the surface of anything exposed to air at the time of the accident. The main radioactive nuclides are now 137Cs and 134Cs. However, the radioactive nuclides were hardly moved from the original point that they touched, which was very difficult to estimate from our understanding of the chemical behavior of cesium. Since the carrier free Cs amount is extremely small, there is an obvious difference between the behavior of the fallout and that of the macroscopic Cs.
