UNITED NATIONS (Reuters) - An increase in thyroid cancer among children is unlikely after the meltdown at Japan's Fukushima nuclear plant four years ago, but it remains unclear exactly how much radiation children in the vicinity of the plant were exposed to, the United Nations' nuclear watchdog said in a report released on Monday.
Increased thyroid cancer is generally the leading health concern after exposure to nuclear radiation, but that may not be the case after the accident at Tokyo Electric Power Co's Fukushima Daiichi plant in March 2011, the Vienna-based International Atomic Energy Agency said.
