This cohort will later explore the iatrogenic effects of low-dosage of ionising radiation, carcinogenic and non-carcinogenic effects. null France Individuals General population Male Female Child, Preschool (2 to 5 years) Child (6 to 12 years) Young Adult (19 to 24 years) Children under 15 years old admitted to radiology services for initial examination after 1st January 2000 - Children permanently living in France - not diagnosed with cancer during first year after computerised tomography (CT) scan.
