Assessment of radiation knowledge and awareness among radiology staff in tertiary hospitals: a study in Wuxi, China

A number of previous studies have shown that the knowledge of radiation dose and its associated carcinogenic risk among radiology staff is inadequate. Underestimation of radiation dose and cancer risk in diagnostic procedures is prevalent, which may lead to suboptimal scanning parameters and potential overuse of radiation in daily practice. This study aimed to evaluate the knowledge of radiation dose and associated risks in common diagnostic radiological examinations among radiology staff in comprehensive tertiary hospitals in Wuxi, China. An online questionnaire survey was conducted among radiology staff from seven general tertiary hospitals.
