This paper aims to clarify the effect of 137Cs internal exposure after the Fukushima Daiichi NPP accident. Using data of approximately 34,000 examinees of a whole-body counter conducted by the Hirata Central Hospital from October 11, 2011 to January 31, 2013, the relationship between internal radiation dose and food ingestion is empirically and quantitatively demonstrated. As a result, elderly people who lived near the Fukushima NPPs and have daily eaten local rice and fungi have a tendency to display higher internal radiation dose.
