| Abstract | ||
| background: Since the discovery of the roentgen ray in 1895, radiography and fluoroscopy remained the stanchion of diagnostic radiology for decades. During fluoroscopy procedures the radiation exposure of staff arises due to scattered radiation. The adequacy of shielding for secondary radiation depends on the material and thickness used for this purpose. Aim of the study: This work studies the secondary shielding for the control booth of fluoroscopy room in AL –Hussaine teaching hospital of Karbala city, Iraq. Materials and method: By considering the fluoroscopy room design and the radiographic devices profiles used, the clinical total workload per week and total workload per patient have been computed and its distribution according to the most widely used voltages has been determined by recording the actual clinical technical values of maximum ,average and minimum As and the corresponding values of kilovolt peak for 217 patients over five months. As a diagnostic x-ray radiation shielding reference, the National Council on Radiation Protection and Measurements report No.147 (NCRP report No.147) and XRAYBARR computer program have been used to compute the secondarybarrier thicknesses of the control booth of the fluoroscopy room for lead and glass. Results and discussion: It is found that the total workload per week of NCRP report No.147 is about equal that of calculated for average state and about 1.6 times that of calculated workload for busy state. Conclusion: The shielding status of control both was quite sufficient ,and about 1 mm of lead was used to shield the front wall and lead glass was used in the shielding of observation window | ||
