Outline of Final Research Achievements

We investigated radiocesium and 40K in peach during the maturity of its fruits chronologically for 8 years.In the investigation during one crop period, the concentration of radiocesium in young fruits 15 days after the full bloom was the highest, and this result was common in all of the investigated years. When looking at a chronological transition, the concentration of radiocesium in harvested fruits decreased by one third in every year from 2011 to 2013. However, such decrease could not be seen from 2014 to 2017.The transfer factor ratio of 133Cs and 137Cs to fruits is likely to be similar when they are applied at the same time to blueberries.
