in three locations in two cities that are150 kilometers north of Fukushima I Nuclear Power Plant.
In response to the radioactive rice hay found in Fukushima Prefecture that contained up to 500,000 becquerels/kg of cesium, Miyagi Prefecture did the survey of rice hay in three locations in two cities, Kurihara City and Tome City, north of Sendai City. Maximum 3,600 becquerels/kg of cesium was found in the rice hay, which had been used by the cattle farmers to feed their cows.
Sankei Shinbun (7/15/2011) reported the comment of the cattle farmers:
"I am very upset", says a cattle farmer in Tome City in Miyagi Prefecture. "I've been feeding the cows with the rice hay collected from the rice fields last fall. This is a big blow to my farm. I never imagined that the radioactive materials would fly this far. "
The Miyagi prefectural government's instruction to cattle farmers were: "Do not use the rice hay collected after the Fukushima I Nuclear Power Plant accident." So, following the instruction, the cattle farmers were feeding their cows with the rice hay collected last fall.
This is the radiation contour map created by Professor Yukio Hayakawa, the volcanologist at Gunma University. Notice the arm that goes north from the Fukushima I Nuke Plant and curl left. Kurihara and Tome are right below the curl. If only someone had shown the map to the cattle farmers there ...
Or if only someone had shown the cattle farmers the radioactive materials dispersion forecast by ZAMG, German Weather Bureau, or Norwegian Weather Bureau early in the accident, they would have seen that Miyagi Prefecture was almost constantly under the radioactive plume from the nuke plant.
