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.

“There have been massive radiation spikes in Canada because of Fukushima,” said Gordon Edwards, president of the Canadian Coalition for Nuclear Responsibility.

“The authorities don’t want people to have an understanding of this. The government of Canada tends to pooh-pooh the dangers of nuclear power because it is a promoter of nuclear energy and uranium sales.”

Edwards has advised the federal auditor-general’s office and the Ontario government on nuclear-power issues and is a math professor at Montreal’s Vanier College.

In a phone interview from his Montreal home, he said radiation from Fukushima will lead to higher rates of cancer and other diseases among Canadians. But don’t panic. Edwards cautioned that the risk is very small for any particular individual.

“It’s not the risk to an individual that’s the problem but how much society is at risk. When you are exposing millions of people to an insult, even if the average dose is quite small, we are going to see fatal health effects,” he said.

Some impacts may have already occurred in North America. Infant mortality in eight cities in the U.S. Northwest jumped 35 percent after Fukushima, according to an article by internist and toxicologist Janette Sherman and epidemiologist Joseph Mangano on the Counterpunch website in June. The number of infant deaths rose from 9.25 per week in the four weeks prior to March 19 to 12.5 per week in the following 10 weeks, according to U.S. Centers for Disease Control data.

“There has been a dismissiveness about the long-term hazards of nuclear power,” said Dr. Curren Warf, adolescent-medicine division head at B.C. Children’s Hospital.

Warf was on the board of the Nobel Peace Prize–winning U.S. antinuclear group Physicians for Social Responsibility before he moved to B.C. in 2009.

“These were some of the most advanced nuclear power plants in the world. But a natural earthquake and tsunami rendered their safety measures completely meaningless,” he said in a phone interview while on vacation in Tofino on Vancouver Island.

It’s not clear what health impacts British Columbians will face from the fallout from Fukushima, Warf said. But he added, “It should be a warning to Canada, the U.S., and the rest of the world about the vulnerability of nuclear power plants to natural catastrophes. These things have typically been dismissed in much of the planning.”

Dr. Erica Frank agrees. “The main concern I’ve had is we are not paying attention to Fukushima as a warning sign. Given the catastrophic long-term issues and what to do about nuclear waste, I had hoped it would be more of a wake-up [call] than it was,” said Frank, a professor of population and public health in UBC’s faculty of medicine and a past president of Physicians for Social Responsibility.
