摘要
2011年日本福岛县发生七级核事故,本文简述了事故后福岛县儿童甲状腺剂量估计、甲状腺结节或甲状腺囊肿和甲状腺癌发生情况的最新研究进展。结果提示,甲状腺结节和甲状腺囊肿发生率没有明显增加,有研究发现甲状腺癌发生率明显高于日本其他地区。有学者认为高发病率可能与研究中对照人群选择及筛查效应有关。此外,^132Te等短半衰期放射性核素对甲状腺剂量的贡献和甲状腺癌的发生发展有着不容忽视的作用。对核电站运行前后的连续监测及事故后健康评价具有重要意义。
The Fukushima nuclear accident happened in 2011. This article introduced the recent studies about thyroid dose estimation, incidence of thyroid nodule, thyroid cyst and thyroid cancer in the children in Fukushima prefecture after the accident. The results suggested that the incidence of thyroid nodule and thyroid cyst had no significant increase. Nevertheless, the present research noted that the incidence of thyroid cancer was obviously higher than that in other areas in Japan, but high incidence may be due to the choice of the control group or the screening effect. Meanwhile, the contribution of ^132Te to the thyroid dose and the incidence of thyroid cancer might not be ignored. The continuous monitoring before and after the operation of the nuclear power plant and the health evaculation after the accident are of importance.
