Abstract
The purpose of this study was to evaluate the patient entrance surface dose (ESD), organ dose and effective dose for neonates in the special care baby unit (SCBU) up to 28 days after birth. A total of 135 patients were examined during 4 months. ESDs were calculated from patient exposure parameters using DosCal software. Effective doses were calculated using software from the National Radiological Protection Board (NRPB). The mean patient ESD per procedure was 80±0.02μGy. The mean and range of the effective dose per procedure were 0.02 (0.01–0.3) mSv. The radiation dose in this study was higher compared to previous studies. A dedicated X-ray machine with additional filtration is recommended for patient dose reductions.
•Neonate radiation dose has been evaluated using mathematical equation.•Neonates are exposed to unnecessary radiation due to use of unsuitable X-ray machines.•Radiation dose is of concern due to neonate sensitivity and multiple exposures during neonate treatment.•Mathematical equation based on exposure factors is suitable for neonate dose measurements.
