Japan’s industry ministry says it has set no radiation standards for gravel shipments from areas affected by the accident at the Fukushima Daiichi nuclear power plant.
The ministry says the high-level of contamination found in a condominium that had been shipped from Namie, was unexpected because the stones were not extracted just from the surface of the mountain.
The industry ministry also says it will make inquiries to other quarries in the prefecture to find out where their gravel was shipped.
