Workers contaminated with uranium dust at Canadian processing plant

Three workers at a Cameco processing facility in Ontario were exposed to airborne uranium dust in an incident at the Saskatchewan company's Blind River refinery last month, federal regulators say.

The exposure happened June 23 when a worker loosened a ring clamp on a 208-litre drum of uranium oxide yellowcake. The lid blew off, injecting about 26 kilograms of the material into the air.

The worker closest to the drum and two others in the area, who were not wearing respirators, were exposed to the dust.

The drum came from the U.S. company Uranium One's Willow Creek facility in Wyoming. More.
