After the world’s worst nuclear accident in 25 years, authorities in Canada said people living here were safe and faced no health risks from the fallout from Fukushima.
They said most of the radiation from the crippled Japanese nuclear power plant would fall into the ocean, where it would be diluted and not pose any danger.
Dr. Dale Dewar wasn’t convinced. Dewar, a family physician in Wynyard, Sask., doesn’t eat a lot of seafood herself, but when her grandchildren come to visit, she carefully checks seafood labels.
She wants to make sure she isn’t serving them anything that might come from the western Pacific Ocean.
Dewar, the executive director of Physicians for Global Survival, a Canadian anti-nuclear group, says the Canadian government has downplayed the radiation risks from Fukushima and is doing little to monitor them.
“We suspect we’re going to see more cancers, decreased fetal viability, decreased fertility, increased metabolic defects – and we expect them to be generational,” she said.
And evidence has emerged that the impacts of the disaster on the Pacific Ocean are worse than expected.
Since a tsunami and earthquake destroyed the Fukushima Daiichi Nuclear Power Plant last March, radioactive cesium has consistently been found in 60 to 80 per cent of Japanese fishing catches each month tested by Japan’s Fisheries Agency.
In November, 65 per cent of the catches tested positive for cesium (a radioactive material created by nuclear reactors), according to a Gazette analysis of data on the fisheries agency’s website. Cesium is a long-lived radionuclide that persists in the environment and increases the risk of cancer, according to the United States Environmental Protection Agency, which says the most common form of radioactive cesium has a half-life of 30 years.
The Canadian Food Inspection Agency, which monitors food safety, says it is aware of the numbers but says the amounts of cesium detected are small.
“Approximately 60 per cent of fish have shown to have detectable levels of radionuclides,” it said in an emailed statement.
“The majority of exported fish to Canada are caught much farther from the coast of Japan, and the Japanese testing has shown that these fish have not been contaminated with high levels of radionuclides.”
But the Japanese data shows elevated levels of contamination in several seafood species that Japan has exported to Canada in recent years.
In November, 18 per cent of cod exceeded a new radiation ceiling for food to be implemented in Japan in April – along with 21 per cent of eel, 22 per cent of sole and 33 per cent of seaweed.
Overall, one in five of the 1,100 catches tested in November exceeded the new ceiling of 100 becquerels per kilogram. (Canada’s ceiling for radiation in food is much higher: 1,000 becquerels per kilo.)
