This is the main raw material for cement production used in construction. The provincial authorities said that it was radioactive rainwater that had seeped into the ground and invaded and groundwater.

A part of this contaminated sludge was sent to the cement manufacturing company outside the province for the purpose of reuse and the province is conducting this investigation.

For a long time, Japan has not had any regulations on the standard threshold for the use of radioactive sludge into production. Fukushima Prefecture requires the government to soon devise safety measures for workers and methods of dealing with this contaminated mud.

According to the province, the results of measuring radioactivity around a melting furnace on April 28 in Kuniyama City show that the concentration of radioactive cesium in mud is 26,400 becquerels per kilogram, while in coal slag is 334,000 becquerel / kg, high. 1,300 times the concentration before the nuclear incident.
