It seems the Atomic Energy of Canada misled the govt. on the severity of the spills. Interesting, if true, that the govt. didn't really know.
From Sun Media:
Canada's nuclear agency misled the Prime Minister's Office over the nature and extent of a radioactive spill at the troubled Chalk River in December, a senior government official said yesterday.
Lisa Raitt, the natural resources minister responsible for the leaky reactor, told Sun Media yesterday she has ordered a full report on the radioactive spill from the nuclear safety commission.
Raitt said she and her departmental officials received an "e-mail briefing" on the leak the day after it occurred.
"There are some aspects that came out today that we weren't fully aware of," the minister said yesterday.
"I've asked my officials at the (safety commission) to get to the bottom of it, and I'm looking forward to getting a full report."
