Abstract

This research work measured radiation doses (RD) and the variation of scattered radiation (SR) from the incident radiation to the critical organs such as chest, abdomen, skull and pelvic for commonly performed paediatric patients undergoing Computerized Tomography (CT) examinations using well calibrated thermoluminescent dosimeters (LiF-100) attached to the skin in the path of the primary X-ray beam. Two hundred and fifty eight (258) paediatric patients were studied.  The values of the equivalent dose for abdominal CT scan ranged from 23.49 - 55. 26mSv; skill CT scan ranged from 10.07 – 69.94mSv and chest CT scan ranged from 8.60 – 31.94mSv. The chest has the highest SR dose of 37.31 mSv when the incident radiation dose to the pelvic is 38.61 mSv.  Pelvic has the least SR dose of 0.21 mSv when the skull has corresponding incident RD of 69.94 mSv.  The work showed that the choice of exposure parameter should be reviewed.
