The World Health Organization was accused by activist physicians of downplaying the health impact of nuclear fallout from the Fukushima nuclear disaster.
In a New York symposium marking the two-year anniversary of the Fukushima nuclear plant meltdown in Japan, the physicians took issue with WHO's conclusion in a recent report that it did not expect a significant surge in cancer in Japan or elsewhere due to radiation leaks.
"It's a report that was meant to reassure people who, almost certainly, many will develop leukemia and cancer," said Helen Caldicott, whose foundation, the Helen Caldicott Foundation, cosponsored the symposium, along with Physicians for Social Responsibility.
Caldicott said the WHO report, released February 28, had numerous major shortcomings, key issues it "ignored" or "glossed over."
For one, she said, WHO did not take actual radioactive emissions into account, relying on estimates.
The UN health body also did not examine the impacts on children comprehensively, including what the impact would be of eating radiation-contaminated food over a lifetime.
The agency also did not closely examine the impact on workers at the Fukushima plant or on people from the area who evacuated through the plume of radiation that came from the plant, she said.
"As a physician, I abhor what they've done," Caldicott said.
She said data showed that three times as much radioactive xenon, and possibly three times as much cesium, escaped at Fukushima as at Chernobyl, the nuclear plant in the Ukraine that released huge amounts of radioactive particles into the atmosphere after an explosion and fire in 1986.
The WHO report did conclude that the cancer risk was higher for certain groups of exposed people in Fukushima.
That includes a projected seven percent increase in leukemia among males exposed as infants, over what would have normally been, and a six percent higher occurrence of breast cancer among women exposed as infants.
The occurrence of thyroid cancer in females over a lifetime could rise by as much as 70 percent over the normal rate.
But for the general population inside and outside of Japan, WHO said, "the predicted risks are low and no observable increases in cancer rates above baseline rates are anticipated."
