The Fukushima Dai-ichi nuclear disaster raised concerns about the health consequences by exposure to and an intake of radionuclides even at the low-level contaminated areas. We performed surveys to detect the presence of radioactive substances in breast milk and placenta from breast-feeding mothers, and food using the duplicate diet method. The monitoring study suggests that there were no detectable contamination in breast milk and placenta, and a trace level of contamination in food. Then, a trial of risk communication was performed to the citizen using the monitoring information. To assess the effects of educational lecture, a questionnaire survey regarding the radiation health knowledge, risk perception, health issue, and trust was asked to the lecture attendees. The results suggest that to attend the lectures may effective to reduce the anxiety level.
