Leukaemia and myeloid malignancy among prospectively analysed cohorts of persons exposed to low doses (<100 mSv) of ionising radiation at ages under 21 years

Background Substantial evidence links exposure to moderate/high doses of ionising radiation, particularly in childhood, with leukaemia risk. The relation with low-dose (<100 mSv) exposures is less certain, but this is the dose-range most relevant to the general population. We aimed to estimate radiation-associated risk of leukaemia after low-dose exposure in childhood (age <21 years).
