Abstract
Purpose : To evaluate low dose-rate radiation effects on the physical heigh ts of children staying in apartments with Co-60-contaminated steel construc tion. Materials and methods: Children who once resided in radiocontaminated apart ments since early 1983 were examined for height and body weight status from age 1 month to 18 years and before they moved out of the apartments. The p hysical heights and body weights of 21 898 age- and sex-matched non-exposed children from a nationwide school surveillance in 1997-98 were taken as co ntrols. The physical height data were shown as height percentiles (HP) comp ared with reference children and age-specific relative height differences ( RHD). Results: HP and RHD in 48 exposed boys and 37 girls were analysed using gen eralized estimating equations (GEE), which accounted for multiple measureme nts and correlation between these measurements in the same individuals duri ng this period. After adjusting for effects from parental heights and body mass index (BMI), clear dose-related decreases in HP and RHD were observed in the exposed boys with a cumulative exposure >60 mSv. Conclusions : Prolonged low dose-rate gamma -radiation exposure was exposur e. One hundred and twelve children in Bikini associated with adverse effect s on the physical heights of growing boys, but were less apparent in the ex posed girls.
