UNITED NATIONS, Nov. 11 (UPI) -- Low levels of radioactive particles have been detected in the Czech Republic and elsewhere in Europe, the U.N. nuclear agency said Friday.
The International Atomic Energy Agency said the radioactive iodine-131 particles do not pose a public health risk.
The IAEA said it was trying to determine the source of the particles but said it did not believe they came from Japan's damaged Fukushima nuclear power plant.
Officials in the Czech Republic first informed the IAEA of the raised radioactivity levels detected at several sites in late October, the agency said.
The iodine could have leaked during production of radiopharmaceuticals, Czech nuclear safety chief Dana Drabova said, adding Czech experts were almost certain the source was abroad.
