Abstract

Backgroud:One of the most frequent radiological examinations is the child's thorax. Children have high organ sensitivity to radiation because their organs are not yet mature. The purpose of this study was to determine the radiation dose received by children during the examination of the thorax at Instalasi Radiology Rumah Sakit Paru dr.

Results: Results of measurement of radiation absorbed dose for children 1-4 years old highest by 0.116 mGy and the lowest was 0.044 mGy. For children 5-9 years the highest absorbed dose of 0.130 mGy and the lowest was 0.036 mGy, while for children 10-15 years acceptable dose of 0.043 mGy.
