Please note that the Workshop venue is in Fukushima prefecture, 80 km away from the Fukushima Dai-ichi Nuclear Power Plant.
The radiation levels there are low (0.1~0.2 μSv/hr) due to the distance and surrounding mountains, while the natural level was 0.06~0.08 µSv/hr.
Therefore the venue is not at all dangerous to any level to the participants.
By choosing this venue we also wanted to set a sign to the public that the science community is able to scientifically deal with the accident.
