Radiation Exposure in Pediatric Intensive Care Unit Patients: How Much Is Too Much?

We aimed to determine median cumulative radiation exposure in pediatric intensive care unit (PICU) patients, proportion of patients with high radiation exposure (above annual average radiation per person of 6.2 mSv), and determine risk factors for high exposure. This was a retrospective chart review of PICU patients up to 18 years of age admitted to a large community hospital over 2 years.
