Ecosystem Affected
The government didn’t say how the milk and spinach became contaminated, making it difficult to assess the risks, Lam Ching-wan, a chemical pathologist at the University of Hong Kong School of Medicine, said by telephone.
“They should seriously think about restricting any agricultural products in that area,” he said. “It seems that the whole ecosystem could be affected, so they shouldn’t take any chances.”
One millisievert, a measure of radioactivity levels, in a liter of milk consumed by a six-year-old child would increase the risk of cancer by 0.017 percent, Lam said. A full-body CT scan would produce exposure of 12 millisieverts, according to the World Health Organization.
Japan will check the source of contaminated milk and spinach and will recall the products that show higher than standard radiation levels, Kyodo News said, citing Kohei Ohtsuka, vice minister of the Ministry of Health, Labor and Welfare.
