Our estimates of neonatal radiation exposure fall short of reality.

Unlabelled: The purpose of this study is to evaluate radiation exposure in newborns undergoing imaging tests during the first 30 days of neonatal intensive care unit (NICU) hospitalization. A retrospective cohort study was conducted from November 2018 to April 2019 with newborns admitted to the NICU. Thermoluminescent dosimeters (TLD-100) measured radiation emitted during imaging exams over 1 month, with a comparison between measured and estimated radiation.
