Title Is occupationally induced exposure to radiation a risk factor for thyroid nodule formation?
Bibliographic information May-June 1996, Vol.51, No.3, p.177-180. 9 ref.
Abstract The prevalence of thyroid nodules was studied with ultrasonography in a group of 44 male hospital workers occupationally exposed to X-rays during 23.5 ▒ 6.4 years. The control group consisted of 88 non-exposed male workers. Thyroid nodules were detected in 18 (41%) of the exposed workers and 11 (13%) of controls. Thyroid function tests were performed in all subjects and found to be in the normal range. The younger subjects of the first group appeared to be at a particular high risk of nodule formation. The nodules were statistically more frequent in subjects occupationally exposed for more than 20 years, compared with those exposed for 10-19 years and with controls. The results of this preliminary study suggest that long-term, low dose occupational exposure to radiation may be a risk factor for thyroid nodule formation.
