http://www.agreenroadproject.org Highly radioactive snow with counts of up to 65 CPM was measured with Geiger Counter in January of 2013. This snow fell in an area that is 25 km from Fukushima Daichi. Minamisōma is a city located in Fukushima Prefecture, Japan. As of May, 1, 2011, the city has an estimated population of 68,745 and a population density of 60 persons per km². The total area is 398.50 km². The Japanese government says this area is ‘safe’ to live in, as of 2012. Minamisōma is about 25 kilometres (16 miles) north of Fukushima I Nuclear Power Plant, the site of the nuclear accident that followed the 2011 Tōhoku earthquake and tsunami.
Geiger counter (at Wiki page, not in video above) showing radiation at Minamisoma: 0.532 μSv/h. This equates to an annual radiation dose of 4.66 millisieverts, compared to the government’s criteria for ‘safe’ return residents at 20 millisieverts per year. The video The pre Fukushima background radiation was a maximum of 1 millisievert exposure per year.
