It can take two to three months for the radioactive fallout of iodine-131 from Japan's Fukushima Dai-ichi Nuclear Plant to dissolve in Shanghai, local experts said today.

The radioactive fallout is carried to the city through atmospheric circulation, not by the wind, said experts with the Shanghai Radiation & Environment Monitoring Agency.

They told the public not to overreact because iodine-131 found in Shanghai is extremely low in level and poses no threat to human health. "Plutonium detected in the soil near the crippled nuclear plant won't affect Shanghai as plutonium isn't a volatile matter," said Wang Mingxia, senior engineer at the agency. "It will only affect areas near the plant."

Shanghai and other coastal areas including Jiangsu, Zhejiang, Guangdong and Guangxi all detected very small amount of iodine-131 yesterday after Heilongjiang Province first reported traces of iodine-131 on Saturday.
