Radiation protection in pediatric radiology deserves special attention where children are more sensitive to radiation than adults This study is concerned with the measurements of pediatric entrance surface dose (ESD) using thermo luminance dosimeter (TLD, LIF100) for patients ranging from age intervals: 0.1 -5 years, 5-10 years and 10-16 years . A central public pediatric hospital and 120 Egyptian patients were included in this investigation . By careful selection of patients three types of simple radiography were select ;(50chest,35abdomen and 35 skull). Pediatric chest examinations are the most frequent radiological examinations comparisons were made between these doses and diagnostic reference levels (DRLs).

The results showed that mean patient skin doses measured with TLD for age ranged from 10-16 years old were 0.20 mGy 14%, 1.10 mGy 23% and 1.00 mGy 40% for chest, abdomen and skull examination respectively. The mean ESD values are found to be within the range ESD reference values except for chest examination.
