Japan : Gov't - Burying contaminated soil into ground works

Article from NHK News :

" The Japanese government plans to inform schools in Fukushima Prefecture that burying radiation-contaminated topsoil into the ground is an effective way to reduce its radiation level.

The education and science ministry concluded this after conducting an experiment at a school in Fukushima City on Sunday. The ministry says that burying contaminated soil 50 centimeters underground reduced the overall radiation level by 90 percent.

After the nuclear accident at the Fukushima Daiichi power plant, schools in the prefecture have been restricting outdoor activities. Radiation levels in soil at all the schools, except for one, remain within the official limit for children playing outdoors.

Schools in the cities of Koriyama and Date have removed the topsoil in their schoolyards as a precaution. But schools have not been able to get the soil transported away from the premises because of the lack of government disposal guidelines for irradiated soil.

The government will report its latest findings to the prefecture's education board and the Nuclear Safety Commission on Wednesday."
