Pyongyang, September 1 (KCNA) -- Nuclear contamination is getting serious in Japan, making trouble.

Incinerator dust and ash with too much radioactive cesium to allow it to be buried has been found at 42 facilities in Tokyo, Chiba, Iwate and three other prefectures as well as Fukushima, the Environment Ministry said Saturday.

Meanwhile, a small amount of radioactive cesium was detected in raw rice in Nihonmatsu, some 60 kilometers from the crippled Fukushima Daiichi nuclear power plant.
