Public Perception and Knowledge of Radiation Risks From Diagnostic Imaging

Background: Diagnostic imaging plays a crucial role in modern medicine but exposes patients to varying levels of ionizing radiation, which can increase long-term health risks if not properly managed. Aim and Objective: To assess public knowledge, perception, and practices regarding radiation risks from diagnostic imaging, and to identify socio-demographic factors influencing awareness and safety behaviors. Patients and Methods: A cross-sectional study was conducted at Ibn Sena Teaching Hospital, Mosul, Nineveh Governorate, from 5 July 2025 to 5 November 2025. A total of 100 participants were randomly selected from outpatient clinics. Data were analyzed using SPSS version 27, with frequencies and percentages reported, and associations assessed using Chi square tests (p < 0.05). Results: The study included participants with a balanced gender distribution (48% male, 52% female) and predominantly urban residence (70%). Overall, 55% demonstrated moderate knowledge of radiation risks, 30% had good knowledge, and 15% had poor knowledge. Awareness of device-specific radiation varied, with 90–95% correctly identifying that MRI and ultrasound do not involve ionizing radiation, while 60–65% recognized higher risks from CT scans and sensitivity in children. Attitudes were generally cautious, with 75–80% agreeing that patients should be informed and awareness improves safety. Conclusion: The study revealed that the public demonstrates moderate knowledge and generally cautious attitudes toward radiation risks VIII from diagnostic imaging, with higher awareness among educated and younger participants.
