After Japan’s Fukushima catastrophe, Canadian government officials reassured jittery Canadians that the radioactive plume billowing from the destroyed nuclear reactors posed zero health risks in this country.
In fact, there was reason to worry. Health Canada detected massive amounts of radioactive material from Fukushima in Canadian air in March and April at monitoring stations across the country.
The level of radioactive iodine spiked above the federal maximum allowed limit in the air at four of the five sites where Health Canada monitors levels of specific radioisotopes.
On March 18, seven days after an earthquake and tsunami triggered eventual nuclear meltdowns at the Fukushima Daiichi plant in Japan, the first radioactive material wafted over the Victoria suburb of Sidney on Vancouver Island.
For 22 days, a Health Canada monitoring station in Sidney detected iodine-131 levels in the air that were 61 percent above the government’s allowable limit. In Resolute Bay, Nunavut, the levels were 3.5 times the limit.
Meanwhile, government officials claimed there was nothing to worry about. “The quantities of radioactive materials reaching Canada as a result of the Japanese nuclear incident are very small and do not pose any health risk to Canadians,” Health Canada says on its website. “The very slight increases in radiation across the country have been smaller than the normal day-to-day fluctuations from background radiation.”
In fact, Health Canada’s own data shows this isn’t true. The iodine-131 level in the air in Sidney peaked at 3.6 millibecquerels per cubic metre on March 20. That’s more than 300 times higher than the background level, which is 0.01 or fewer millibecquerels per cubic metre.
