Title Risk of thyroid nodules in subjects occupationally exposed to radiation: A cross sectional study
Bibliographic information Aug. 1995, Vol.52, No.8, p.500-504. 18 ref.
Abstract Cross-sectional study to examine by ultrasonography the prevalence of thyroid nodules in medical workers occupationally exposed to X radiation at a hospital in Pisa, Italy. Fifty male medical workers exposed to radiation were randomly matched for age with 100 male workers not occupationally exposed to ionizing radiation who lived in a slightly iodine deficient area (control group 1) and with 100 male workers not exposed to radiation who lived in Pisa (control group 2). Of the occupationally exposed subjects, thyroid nodules were detected in 19 (38%). Among controls, thyroid nodules were detected in 19 (19%) subjects of control group 1 and in 13 (13%) of control group 2. Comparison of exposed and control groups, stratified into 30-39, 40-49 and 50-59 year old age subgroups, showed a higher significant relative risk for thyroid nodules in the exposed subjects. The results suggest that occupational exposure to radiation may be a risk factor for thyroid nodules.
