Muscle radiocesium concentration in Japanese monkeys according to level of soil radiocesium contamination at capture locations, and capture periods.

*One-way analysis of variance with a Bonferroni post-hoc analysis showed that the mean muscle radiocesium concentration in monkeys captured in areas with a soil contamination level of 100,000–300,000 Bq/m2 was significantly higher than that in monkeys captured in any of the other 3 areas (P<0.001).
**In monkeys captured in areas with a soil contamination level of 100,000–300,000 Bq/m2, a significant difference was observed in mean muscle concentration between monkeys captured between December 2011 and April 2012 and those captured during other periods (P<0.001).
