Knowledge and Adherence to Radiation Protection among Non-Radiation Health Care Workers at Two Operating Theatres in Windhoek, Namibia.

Abstract: Background: In operating theatres, diagnostic radiography is used to capture images during surgical operations. With the growing use of fluoroscopy, there are concerns about increased radiation exposure to healthcare workers such as doctors and nurses. Thus, assessing HCWs' knowledge and adherence to radiation protection is crucial to prevent overexposure, radiation-related health issues, and ensure patient safety. Objective:The study aimed to assess the knowledge of non-radiation HCWs regarding radiation protection and determine the level of adherence to radiation protection in two theaters. Methods: A quantitative descriptive research methodology was used. Data collection involved a questionnaire, and participants were selected through a simple random sampling method. Data were analyzed using SPSS version 26. Results: Fifty-eight non-radiation HCWs participated. Most (77.6%) were female with nurses comprising the largest demographic (62.1%). Most participants (53.4%) lacked prior education in radiation protection. Concerningly, 70.7% did not use dosimeters during theater radiography, which is a requirement for radiation protection. No significant association was found between participants' allocated hospital and the level of knowledge, but a significant association (p = 0.027) was found between participants' allocated hospital and adherence levels. Conclusion: The findings suggest inadequate knowledge and adherence to radiation protection. Therefore, education on radiation protection must be mandated, and measures should be taken to enforce adherence.
