General objective: the goal of this study is to evaluate the risk of radiation-induced cancer or leukaemia associated with use of CT during early childhood (first scan carried out between the ages of 0 and 10 years), and to quantify the relationship between exposure to ionising radiation and the onset of the pathologies being studied. Secondary objective: to study any possible modifying factors (age at exposure, gender etc.) in this dose-response relationship.

General Objective: To evaluate the effect of psychological, genetic and anamnestic variables on addiction at two years Secondary Objectives: - to highlight intermediate traits associated with addictive disorders at two years - to highlight the effect of gene x environment interactions on the development of dependence.

1. Determine the cognitive score at 8 years old.
2. Determine wether the child is schooled in general or specialized school.

Study on the increased risk of cancer, including lung cancer, after chronic exposure to ionising radiation, including alpha emitters (radon descendants, uranium dust). Professional cofactors and smoking are taken into account. Secondary objective: The cohort study benefits from high quality individual registration of exposure to various carcinogens on an annual basis, as well as long-term follow-up (over 20 years on average). All causes of death are recorded regularly. It is also possible to study risks other than cancer in this cohort, including the risk of cardiovascular or respiratory death. The extrapolation of risk per unit of exposure enables the assessment of low-dosage risk, at levels regularly encountered by some of the French population. This is especially true for the estimation of cancer risk per unit of radon exposure in the home.
