TOKYO —

High levels of radioactive cesium have been detected in ash from firewood used in stoves and fireplaces at homes in Nihonmatsu in Fukushima Prefecture, according to the Environment Ministry.

Although the Forestry Agency has already advised that firewood containing 40 becquerels or more of radioactive cesium per kilogram should not be sold or burned, firewood ash containing over 1,000 times that amount has been found in the garden of one home, TV Asahi reported.

The Environment Ministry collected the ash for inspection and found it contained 43,780 becquerels per kilogram, far exceeding the 8,000-becquerel limit for household waste. The ministry said firewood containing such high levels of radiation should be disposed of safely by the central government.

The firewood in question had been kept outdoors since before the start of the nuclear crisis at Tokyo Electric Power Co’s Fukushima Daiichi nuclear power plant in March last year, the environment ministry said. Firewood left outdoors in other locations was also found to contain between 104 and 4,395 becquerels of radioactive cesium per kilogram, TV Asahi reported.
