Fukushima city removing radioactive topsoil in schools 27 Apr 2011 A city in Fukushima Prefecture started Wednesday to remove topsoil from playgrounds in its elementary and nursery schools, following radiation leaks from a crisis-hit nuclear power plant nearby. Heavy machinery began scooping off surface soil at Kaoru Elementary School and Tsurumidan Nursery School in Koriyama, city officials said, adding that the removed soil will be 'discarded' in landfills in the inland city.
