VIENNA, March 18 (Reuters) - Very low concentrations of radioactive particles believed to have come from Japan’s Fukushima nuclear power plant have been detected on the U.S. west coast, diplomatic sources said on Friday.
The level of radiation was far too low to cause any harm to humans, they said.
One diplomat, citing information from a network of international monitoring stations, described the material as “ever so slight” and consisting of only a few particles.
“It is very low level,” another source in Vienna said. (Reporting by Fredrik Dahl and Sylvia Westall; editing by Tim Pearce)
