Findings from Risk of Pediatric and Adolescent Cancer Associated with Medical Imaging (RIC) a cohort study of 3 700 000 children from Canada and the U.S. found a "significant dose-response relation between cumulative radiation dose to bone marrow and haematologic malignancies risk." The RIC study further found that susceptibility of children to radiation-induced cancer is high due to longer life expectancy compared to adults. In addition, a European EPI-CT study indicates a "50% higher risk among children undergoing two or three CT scans than among those undergoing one scan."
