Abstract

A survey of the entrance surface doses in the routine radiography of children in eastern Nigeria has been carried out in three hospitals, using thermoluminescence detectors. Chest, abdomen, lumbar spine, skull and pelvis were covered in this study. Findings reveal that doses are higher than the recommended reference values elsewhere, as well as values reported for Sudan. The mean percentage difference in entrance doses for chest radiography for this study and an earlier one carried out for three hospitals in the west of Nigeria is about 44.7%. The high doses are traceable to a lack of standardization in procedure, resulting in use of low tube voltages and high currents for examination, as well as the status of facilities in the area. Recommendations are made for immediate corrective measures to lower the doses.

Keywords: Entrance surface dose; exposure; kilovoltage; pediatric; radiography.

Comparison of mean ESDs for the three hospitals, for chest, abdomen and skull in this work (TW) with data from three other hospitals in Nigeria from the study by Ogundare et al.,[19] and from UNSCEAR.[20] The age range 0-1 month was merged with 1 month - 1 year for this comparison. The values plotted in the figure are therefore mean values for the two age groups (0-1 month and 1 month - 1 year) in the references[19] and,[20] respectively.
