Major Factor of the hotspot
Administrators in this facility called Kawasemi no Sato took gutter's mud and under a downspout mud. They threw it away in the bush along with the building. Even though the Ministry of the Environment acknowledges that gutter's mud is highly contaminated. Because of the vast amount of the mud, it makes ambient radiation readings 3 meters away from the center of the hotspot quite high.
