TOKYO (AP) — Japan said Tuesday it plans to use some slightly radioactive soil stored near the tsunami-wrecked Fukushima nuclear plant on flower beds outside Prime Minister Shigeru Ishiba’s office to show it is safe to reuse.

The soil was removed from across the Fukushima prefecture as part of decontamination work following the 2011 nuclear disaster and has since been in interim storage. Some of it has since reached levels safe enough for reuse, officials say.

Using the soil at Ishiba’s office in Tokyo is aimed at reassuring the public it is safe. The government said that it plans to reuse the soil for flower beds and other purposes within the grounds of government agencies. The plan is based on guidelines set by the Environment Ministry in March and endorsed by the International Atomic Energy Agency.

The Fukushima disaster resulted in large amounts of radioactive materials spewing out from the plant, polluting surrounding areas.

Japan is stuck with large volumes of the dirt, chopped trees and other debris collected during intensive decontamination work. It has 14 million cubic meters of dirt and other materials — enough to fill 11 baseball stadiums — stored at a sprawling outdoor facility straddling the towns of Futaba and Okuma, near the Fukushima plant.
