  1. Is occupationally induced exposure to radiation a risk factor for thyroid nodule formation ?

    Article - En anglais

    The prevalence of thyroid nodules was studied with ultrasonography in a group of male hospital workers (n=44) who had been exposed occupationally to x-rays.

    This group was compared with a group of nonexposed workers (n=88) who were age-and sex-matched with the exposed workers.

    Thyroid nodules were detected in 18 (41%) of the exposed workers, compared with 11 (13%) of the nonexposed controls.

    Both groups were subdivided with respect to age (i.e., 30-39 y, 40-49 y, 50-59 y), and there was a higher and significant relative risk for thyroid nodule formation in the exposed group.

    We also divided the groups into subgroups according to levels of exposure (i.e., nonexposed, exposed for<20 y, and exposed for>20 y), and a significant result was obtained with the linear-trend chi-square test.

    The preliminary results of out study suggest that occupationally induced exposure to radiation may be a risk factor for thyroid nodule formation.
