After occurring the nuclear catastrophe, an area within 14 miles of Fukushima Dai-ichi nuclear power plant was designated as the No-entry zone. Japanese government notified each prefecture to treat all of cattle by killing in the area after two months. It is so as not to make distribute contaminated meat by radiation. Farmers couldn't help but obeyed national policy having to live with it because they were forced to evacuate the area and couldn't make any prediction for tomorrow.
However, some cattle ranchers who can't accept the situation and have fed cows without taking care of their own exposure appeared. A farmer have still lived in a banned area against living in, another frequents from temporary housing 50 miles away from there once two days. A combined team of universities that monitors health damages of exposed cows started to work, also. The theme of study is the world's first low dose exposure of large animal. However, this is a country that immediately wants to wipe out scars of the accident although it was a terrible disaster depends on a national policy. They don't cooperatively work even for a research that appears to be valuable for mankind.
