搜了一下：此人：James Fagin（of New York's Memorial Sloan-Kettering Cancer Center, who studied thyroid cancer in children living near Chernobyl）的研究：
Ａbout 6,000 Chernobyl victims developed thyroid cancer, all of them younger than 18 at the time of the meltdown. Radioactive iodine doesn't appear to pose a threat to people 30 and older. Other concerns are strontium-90, which is drawn to bone, and two forms of radioactive cesium, which persists in nature for decades and can work its way into the food chain.
Strontium-90, however, is too heavy to travel far from the reactors. Cesium is present in much lower amounts than radioactive iodine.
另有报道放射性碘导致的甲癌死亡很低他们当中只有１０几个人死于甲癌．
