Establishment of Nagasaki University/ Kawauchi Village Reconstruction Promotion Base in Kawauchi Village (April 2013)
1.Evaluation of effectiveness of decontamination through the measurement of radionuclides in soils.
2.Evaluation of risks of internal exposure through the measurement of foods and waters.
3.Health consultation with inhabitants according to the results of measurements.
4.Health promotion of inhabitants.
Mission
【Frequently asked questions by residents】 ●Food and water safeties in the village. ●Children’s health risks residing in the village. ●Basic knowledge about radiation. ●Future prospect the return to their home.
【My mission】 Working as a public health nurse in charge of the health consultation concerning radiation exposure and health effects.
Individual consultation on radiation exposure and health effects
Establishment of radiation health risk sciences, corresponding to social needs after the accident at Fukushima nuclear power plant.
Conclusion
Close cooperation between Nagasaki University and Kawauchi village should be a model for reconstruction after the accident at Fukushima nuclear power plant.
With the Atomic Bomb Disease Institute playing a central role, we plan to continue our activities as we offer Fukushima support from Nagasaki University.
