Description
Summary:Purpose: To review the estimates of the risk of childhood cancer per unit dose of radiation received in utero derived from the largest case-control study of obstetric X-ray examinations and to compare them with the childhood cancer risk coefficients obtained from the cohorts of Japanese atomic bomb survivors irradiated either in utero or as young children. Materials and methods: Data from the Oxford Survey of Childhood Cancers (OSCC) case-control study of foetal exposure to diagnostic X-rays and from the cohort studies of the Japanese survivors of the atomic bombings of Hiroshima and Nagasaki were used, together with associated dose estimates. Excess relative risk and excess absolute risk coefficients were compared, fully taking into consideration the various sources of uncertainty. Results: The excess relative risk coefficient for childhood (
