Abstract
Computed tomography (ct) scanners have made significant contributions in diagnosing patients’ illnesses in hospitals and health facilities around the world accurately and effectively. However, because the dose produced is very high compared to other x-ray irradiation apparatus, there has been an increased concern among paediatric medical experts and the public in general regarding the long-term effects caused by the exposure. The international atomic energy agency (iaea) and international commission on radiological protection (icrp) have recommended dose reference levels (drls) as a strategy to optimize doses received in pediatric patients. The purpose of this research is to estimate computed tomography dose index volume (ctdivol), dose length product (dlp) and effective dose (ed) values for children in tunku azizah hospital (hta), kuala lumpur and selayang hospital (hs), selangor. A total of 654 ct x-ray examinations were conducted at hta, while 304 ct x-ray examinations were conducted at hs between january 2020 and december 2021.
