The Fukushima Daiichi NPP accident of March 2011 heavily contaminated the Fukushima soils by radioactive cesium.

Past experiences show that people living in such regions become internally contaminated due to cesium ingestion, and hence all necessary measures must be taken to reduce the risks to people.

In order to clarify the situation, Prof. Hayano proposed in the summer of 2011 to measure the cesium concentrations of school lunch. The project is now funded by the ministry of education, and has shown that school lunch served in Fukushima (and elsewhere) is practically cesium free. He is am also helping several hospitals in Fukushima in assessing the 134Cs and 137Cs body burdens with whole-body counters. So far, some 50,000 people have been measured and the it has been shown (quite surprisingly) that >99% of Fukushima citizens have no detectable-level of radioactive cesium in their bodies.

In the colloquium, Prof. Hayano will briefly discuss the sequence of events following the earthquake, various monitoring results, food screening procedures and results, followed by a preliminary estimate of radiation doses to the public.
