Abstract:
A fixed population of about 120,000 subjects was selected from those A-bomb survivors and unexposed controls for the purpose of follow-up studies on their late health effects. One hundred twelve cases of thyroid cancer were found in the study period between 1958 to 1979. The relative risk increased with thyroid dose: the excess relative risk per Gray was 1.1. The prevalence of thyroid diseases was evaluated in 2,587 subjects in Nagasaki: one or more diagnoses for thyroid diseases were made in 447.
