Background: Recent reports have indicated that infants and young children have a higher sensitivity than older children and adults to radiation exposure and the potential for harmful side effects.
Objective: To determine whether the present landmarks used in film positioning result in unnecessary radiation to non-thoracic structures on chest radiographs in the pediatric and neonatal population.
Materials And Methods: Chest radiographs of 195 pediatric patients and 149 neonates were analyzed for extent of radiation field to non-thoracic regions.
