Wild Edible Fungi

We measured activity levels of radioisotopes cesium-134 (134Cs) and cesium-137 (137Cs) in wild edible fungi, mineral soil, and surface litter of the west coast of North America from southern California to northern Vancouver Island after the Fukushima nuclear accident. All activity measurements were below United States governmental limits for human health.137Cs activity increased to the north in mineral soils and fungal samples, whereas134Cs activity increased to the south in surface litter samples. Chanterelles (Cantharellus spp.) did not significantly bioconcentrate either radioisotope, but chanterelle activity levels were correlated with those of mineral soil. Activity levels demonstrated a high degree of variability, even in samples from the same site. In most cases, the level of137Cs activity was substantially higher than that of134Cs, suggesting that137Cs was present in the environment prior to the Fukushima release.

Medical Professionals

The Fukushima nuclear accident in March 2011 posed major threats to public health. In response, medical professionals have tried to communicate the risks to residents. To investigate forms of risk communication and to share lessons learned, we reviewed medical professionals’ activities in Fukushima Prefecture from the prefectural level to the individual level: public communication through Fukushima Health Management Surveys, a Yorozu (“general”) health consultation project, communications of radiological conditions and health promotion in Iitate and Kawauchi villages, dialogues based on whole-body counter, and science communications through online media. The activities generally started with radiation risks, mainly through group-based discussions, but gradually shifted to face-to-face communications to address comprehensive health risks to individuals and well-being. The activities were intended to support residents’ decisions and to promote public health in a participatory manner. This article highlights the need for a systematic evaluation of ongoing risk communication practices, and a wider application of successful approaches for Fukushima recovery and for better preparedness for future disasters.
