Radionuclides were released into the environment in the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. Radiocesium (Cs-134+137) concentrations in most agricultural products became lower than the detection limit (∼10 Bq kg{sup -1}) from June 2011, and the concentrations have remained low. However, some wild food materials such as meat of game animals (e.g., bear and wild boar) caught in Fukushima and surrounding areas some times showed higher values than the detection limits. In this study, monitoring data on game animal meat were summarized to understand the amount of activities found in wild animals and the activity distribution in the contaminated areas. Concentration data are available from monthly reports issued by the Ministry of Health, Labour and Welfare. Data were collected on wild boar (Sus scrofa), deer (Cervus nippon), Asian black bear (Ursus thibetanus), Japanese pheasant (Phasianus versicolor), and duck (e.g. Anas poecilorhynch). There is a tendency that the concentration decreases with distance from the FDNPP; in order to compare the Cs-137 concentrations among animals, one collection site was selected. The results showed that the concentration was in the following order within one year: Asian black bear>wild boar> deer >duck and Japanese pheasant. Bear and boar are omnivorous animals and their feeding pattern would affect the concentrations in their meats. (authors)
