Abstract:
The medical application of radiation can induce radio-biological effects which makes it necessary to ensure some safety precautions, of which, room shielding is one of those safety measures. The aim of this study was to assess the lead wall lining thickness of the radio-diagnostic room of Turai Yaradua Maternity and Children Hospital Katsina. The required lead wall lining thickness was estimated using NCRP 147 formulations. The measured area of the radio-diagnostic room was 39.44 m2. The maximum required lead thickness values were estimated as 1.1 mm and 0.8 mm for erect and supine radiographic positions, respectively, while, the installed lead wall lining thickness was 2 mm. The area monitoring revealed that there was no leakage radiation. Though, the shielding was adequate and there was no leakage radiation, it is however recommended that the radiation workers maintain maximum distance, minimum exposure time and use shielding barrier in order to ensure minimal occupational radiation exposure. Periodic area monitoring is also encouraged in order to prevent radiation exposure of the members of the public.
