Epidemiologic studies of medically and environmentally exposed populations have been central to establishing ionizing radiation as a cause of malignant and benign thyroid tumors. Issues currently under investigation concern low dose effects, age sensitivity, the relative effectiveness of X-rays and iodine-131 in inducing thyroid cancer, and other risk factors. Excess thyroid tumors continue to appear in irradiated populations under study more than three decades after exposure.
对医疗照射和环境照射人群的流行病学研究一直是确定电离辐射为恶性和良性甲状腺肿瘤病因的核心。目前正在研究的问题包括低剂量效应、年龄敏感性、X射线和碘-131在诱发甲状腺癌方面的相对有效性以及其他风险因素。在接受照射三十多年后的受照人群中,仍不断出现甲状腺肿瘤增多的情况。
