|Background: Some above ground nuclear tests conducted from 1949 to 1962 at the Semipalatinsk Nuclear Test Site led to radiation exposure of the public. In the frame of the Hiroshima-Semipalatinsk Project (an NGO activity; Kawano et al., 2003) medical examinations for hypothyroidism, thyroid cancer, and thyroid nodules were conducted. The purpose was to provide documentation that might be used in determining whether these exposures had an impact on public health.
Methods: The study design was a series of cross-sectional studies. Interviews were conducted and questionnaires administered to ascertain information on date of birth, height, weight, family structure, exposure status of family members, place of residence at the time of exposure, the number of deliveries for females, etc. In a second step, urine samples were taken for determining stable iodine concentrations, blood samples were taken to determine the thyroid hormone status, palpations were done to investigate the physical status of the thyroid gland, and finally ultrasound examinations were conducted to better determine the presence and size of physical abnormalities. When indicated, nodule punctures were taken.
Results: 1,287 examinations were carried out among 1,067 study participants. 456 were believed to have been exposed and 577 were not. For 34 participants, the exposure situation could not be determined.
Analyses: To date, risks for hypothyroidism, for thyroid cancer, and for thyroid nodules were analysed (Grosche et al., 2017) in relation to exposure status. Still, there is a lot of information not yet analysed, particularly the parameters describing thyroid function, i.e. T3, T4 and TSH, and medication. Another topic is the development of thyroid disorders over time, which can be analysed for those study subjects with more than one examination.
