Effects of the Fukushima Daichi nuclear accident on children's thyroid gland / 中华放射医学与防护杂志

ABSTRACT

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.
