Radiation trace found on Japan air passengers to S.Korea

South Korean officials detected unusually high levels of radiation on three passengers arriving from Japan on Thursday on the first day of such checks at the country's main Incheon airport, news reports said.

A Japanese man in his 50s who is believed to have lived in the Fukushima prefecture had a reading exceeding 1 microsieverts from his hat and coat, which is several times the normal reading, South Korea's Yonhap news agency said. (Reuters)
