Fukushima Radioactive Cesium Reaches Canada
Scientists say that very little traces of toxic cesium-134 and cesium-137 from Fukushima nuclear power plant have been detected in Canada, Vancouver.
“The detected concentrations are much lower than the Canadian safety limit for cesium levels in drinking water,” John Smith, a research scientist at Canada’s Bedford Institute of Oceanography in Dartmouth, Nova Scotia, said.
Cesium-137 has a half-life of 30 years, but cesium-134 has a half-life of just two years, indicating that the material detected in Vancouver is of recent vintage, and not a product of older nuclear waste,according to the international press.
Traces of contamination from Fukushima might float across the Pacific Ocean and reach the West Coast sometime this year, Ken Buesseler, a senior scientist with Woods Hole Oceanographic Institute and director of the Center for Marine and Environmental Radioactivity (CMER) said.
