Secondary objective: to study any possible modifying factors (age at exposure, gender etc.) in this dose-response relationship. null France Individuals General population Male Female Infant, Newborn (birth to 28 days) Infant (28 days to 2 years) Child, Preschool (2 to 5 years) Child (6 to 12 years) Inclusion of children exposed to at least one CT scan for a nonmalignant pathology: - under 5 years for the 2000-2006 period - under 10 years for the 2007-2013 period.
