[National Council on Radiation Protection and Measurements.; National Council on Radiation Protection and Measurements. Scientific Committee on Risk to the Thyroid from Ionizing Radiation.]. Conclusions. Low dose ionizing radiation exposure would seem to significantly influence levels of free triiodothyronine, free thyroxine, thyroid stimulating hormone, then suggesting a possible increased risk of hypothyroidism in healthcare workers although no relationship could be . Exposure to Ionizing Radiation Summary: Strong evidence has been recorded of a possible connection between thyroid cancer and exposure to ionizing radiation. This evidence is based upon studies conducted at Los Alamos National Laboratory, studies of nuclear workers at other sites, and others exposed to ionizing radiation.
High-dose exposure to ionizing radiation is the only known nongenetic risk factor; the vast majority of cases have an unknown etiology. Methods: We conducted a population-based nested case-control study to evaluate the relationship between a range of birth characteristics and the risk of pediatric thyroid cancer. Using linked birth records and. Background: Exposure to moderate-to-high doses of ionizing radiation is the only established environmental risk factor for thyroid cancer and brain and central nervous system tumors. Considering the high lifetime prevalence and frequency of exposure to dental X-rays, the most common source of diagnostic radiation exposure in the general population, even a small associated increase . Angela M. Leung, The Dose of Ionizing Radiation During Childhood Is Associated with the Prevalence of Thyroid Nodules Even Nearly 60 Years Later, Clinical Thyroidology, /ct;, . Childhood cancer survivors (CCSs) are at increased risk to develop thyroid disease, in particular hypothyroidism, nodular disease and thyroid cancer. Hyperthyroidism is less common but may occur after ionizing radiation exposure, even if the causative mechanisms are not completely clarified.
However, the transfer of inferences from animal studies to humans is perilous. In addition, large gaps in the existing data, the low incidence of thyroid cancer, and the small size of populations available for study make risk derivations uncertain. At best, the potential of radiation exposures to cause human thyroid cancer can only be approximated. CT scans use ionizing radiation which, in high doses, increases the risk of thyroid cancer. This study used mathematical calculations to see how much radiation is absorbed by the thyroid during a neck CT scan. The calculations were then used to estimate the risk of developing thyroid cancer. Risks to the thyroid from ionizing radiation. Report no. Bethesda, MD: National Council on Radiation Protection and Measurement; Huda W, Atherton JV, Ware DE, Cumming WA An approach for the estimation of effective radiation dose at CT in pediatric patients. Although childhood exposure to ionizing radiation is a well-established risk factor for thyroid cancer, the risk associated with adulthood exposure remains unclear. We prospectively examined the association between cumulative, low-to-moderate dose occupational radiation exposure to the thyroid and thyroid cancer incidence in the U.S. Radiologic.
