Abstract
Background: Exposure to ionizing radiations is hazardous to radiological workers, patient’s relatives and patients. The effect may be stochastic or deterministic. Protective apparel keeps the radiation dose received by hospital workers, patients and patient relatives as low as reasonable achievable (ALARA) under normal working conditions. Protective apparels are frequently mishandled in the diagnostic room after use leading to damage.
Objective: This study aimed at assessing integrity of the protective apparel used at the radiology department of a tertiary health institution in Adamawa State of Nigeria.
Methods: From three different hospitals in Yola, 26 pieces of protective apparels were identified, inspected and classified by the hospital, type, manufacturer's name, years it had been used, and the thickness of the lead. With 17 x 14-inch cassette two exposures
were made on each the garment with 70 kVp and 10 mAs with a film focal distance (FFD) of 100cm with a conventional x-ray unit..
Results: The result showed 12 (46.0 %) of the protective apparel studied were defective with split 5 (42.0%), crack 4(33.0%) and hole 3(25.0%) as the most common defect. Correlation of the apparels age and the number of defective protective apparels were statistically not significant (p = 0.166).
Conclusion: In order ensure protective garments provide the best protection possible; there is a need for proper storage and regular quality assurance on the apparels in the radiology departments to ensure radiation protection.
