A Study on Patient Awareness Regarding Radiation Risks Associated with Chest X-Rays

Chest X-rays are a common diagnostic test; however, patient education about the associated radiation risks is minimal, especially in poorly developed nations such as Bangladesh. This study aimed to assess the level of awareness of radiation exposure from chest X-rays in patients and how demographic and experiential factors influence their perceptions. A descriptive cross-sectional survey of 110 adult patients from five private medical centers in Dhaka was conducted from November 2024 to April 2025. Data were collected through structured questionnaires and face-to-face interviews. The majority of the participants (98.2%) had already had a chest radiograph, yet only 43.6% were told about the risks of radiation. Almost half (46.4%) were unconcerned about radiation, whereas 76.4% thought it might be harmful, mostly relating it to cancer and genetic damage. The Internet (47.3%) and medical professionals (30.9%) were the most important sources of information. Educational attainment and previous imaging experience affected awareness. Of note, 81.8% liked more information, and 93.6% preferred educational materials. Despite the extensive use of chest X-rays, awareness remains uneven, and many patients depend on nonprofessional sources. Education gaps were especially evident in individuals with lower levels of formal education. Enhancement of patient education by providing accessible resources and clear communication by medical practitioners is necessary to enhance informed decision making and limit inappropriate radiation exposure.
