Background: After the Chernobyl accident in 1986, children of the contaminated Narodichesky region of Ukraine were obliged to participate in a yearly medical screening. They have been exposed to ¹³⁷cesium (¹³⁷Cs; half-life = 30 years) in contaminated soils, air, and food. Objective: Using a “natural experiment” approach and a longitudinal prospective cohort study design, we investigated the association of soil ¹³⁷Cs and spirometry measures for 415 children using 1,888 repeated measurements from 1993 to 1998. Methods: Mean baseline village soil ¹³⁷Cs measurements, which varied from 29.0 to 879 kBq/m², were used as exposure indicators. A standardized spirometry protocol and prediction equation specific to Ukrainian children were used by the same pulmonologist in all screenings. Results: Children living in villages with the highest quintile of soil ¹³⁷Cs were 2.60 times more likely to have forced vital capacity (FVC) < 80% of predicted [95% confidence interval (CI), 1.07–6.34] and 5.08 times more likely to have a ratio of forced expiratory volume in 1 sec (FEV₁) to FVC% 100 kBq/m²), middle (47 kBq/m²) and low (< 10 kBq/m²) contamination levels and (iv) to calculate the internal doses of 137Cs for variable cohorts with different dose-forming histories (different ages at the start of exposure, its duration and diet contamination, types of soil).
