Radioactive iodine found in Japan tap water

OSAKA - Traces of radioactive iodine have been detected in tap water in Tokyo in the wake of an emergency at a quake-hit Japanese nuclear power plant, the government said Saturday.

Abnormal levels of radioactive iodine were also found in the water supply in the central prefectures of Gunma, Tochigi, Saitama, Chiba and Niigata, said an official at Japan’s science ministry, which is monitoring radiation levels.

But the levels were far below Japan’s legal limit, said the official, who did not want to be named.

Earlier the government said it had discovered abnormal levels of radiation that exceeded the legal limit in milk and spinach from areas near the stricken plant, but they posed no immediate threat to humans.
