CHIBA, Oct. 21 — NHK (Japanese only) is reporting on the discovery of 57.5 microsieverts per hour (µSv/hr) at a vacant lot in Kashiwa, Chiba.
According to Mochizuki’s post on the article, citizens measured 20 µSv/hr on October 18 in an empty area surrounded by houses/factories and reported it to the city government.
When they dug into the ground 20cm deep, the reading was 57.5 µSv/hr.
The city says it’s difficult to assume a link to the Fukushima meltdowns because of the distance underground.
Mochizuki notes that “radioactive particle might have sunk” or radioactive debris from Fukushima may have been secretly abandoned in the area.
