Outline of Final Research Achievements

The objective of this study was to determine the change in concentration of radiocesium 134Cs and 137Cs over time in the muscle of Japanese monkeys inhabiting Fukushima City located 70 km from the Fukushima Daiichi Nuclear Power Plant (NPP), and their health effect of radioactive materials. Cesium concentration in the muscle of monkeys was 6,000 - 25,000 Bq/kg in April 2011 and decreased over 3 months to around 1,000 Bq/kg. However, the concentration increased again to 2,000 - 3,000 Bq/kg in some animals during winter before returning to 1,000 Bq/kg in April 2012. The increasing phenomenon during winter was observed in every year after 2011. The female pregnancy rates in Japanese monkeys were estimated in about 50% since 2008, however, that was reduction in 20% in 2015.
