Exposure to diagnostic low-dose ionising radiation and CT scans is associated with increased cancer incidence in children, according to a study in more than 12 million children and adolescents.

The researchers analysed South Korean National Health Insurance System claims data on a cohort aged up to 19 at enrolment in 2006 and followed to 2015.
