| Outline of Final Research Achievements |
Background: Some above ground nuclear tests conducted from 1949 to 1962 at the Semipalatinsk Nuclear Test Site led to radiation exposure of the public. We conducted medical examinations for hypothyroidism, thyroid cancer, and thyroid nodules with the purpose of providing documentation that might be used in determining whether these exposures had an impact on public health.
Conclusion: There was no indication for an elevated risk of hypothyroidism or thyroid cancer among those who were believed to have been exposed compared to those who were likely unexposed. However, an elevated risk for thyroid nodules could not be ruled out among those living in affected settlements. The strength of these findings is limited by the absence of individual radiation dose estimates.
