Thyroid nodules as related to absorbed dose from iodine-131 in a Ukrainian cohort following the Chernobyl accident
MetadataShow full item record
The Chernobyl accident in 1986 exposed thousands of people to various radioactive isotopes of iodine, particularly iodine-131 (I-131). In subsequent years after exposure, a large increase in thyroid cancer among those exposed as children and adolescents was found, particularly in Belarus, Russia, and Ukraine. Since the natural history of thyroid nodules is not clear, we examined the relationship between the presence of thyroid nodules 12-14 years after the accident and measurement-based individual I-131 thyroid dose estimates. The cohort consisted of 13,008 individuals who were under the age of ...
