Perceptions of Radiation Safety Culture in Medical Imaging by Role

To determine whether radiologic technologists' perceptions of determinants of radiation safety culture differ significantly based on their primary role.

A secondary analysis of deidentified data from 425 radiologic technologists who participated in the Radiation Actions and Dimensions of Radiation Safety questionnaire, a 35-item survey with valid and reliable psychometric properties, was performed. Nine determinants (dependent variables) of radiation safety culture were analyzed in this study. The radiologic technologists worked primarily as staff technologists; shift, team, or modality leads; and managers or directors. Descriptive statistics were used to analyze differences in favorability for the determinants of radiation safety culture by primary role. Games-Howell post hoc tests were conducted to analyze the hypothesis for each determinant.

Four determinants demonstrated significant differences with appropriate observed power between staff technologists, leads, and managers and directors: questioning attitude (P < .001), feedback loops (P < .001), leadership actions (P < .001), and nonpunitive response (P < .001).

The findings indicate that dialogue is needed between all stakeholders to improve the radiation safety culture and that power imbalances caused by the hierarchical system should be considered when seeking to improve the safety culture.

Positional hierarchies in the medical imaging profession affect the perception of radiation safety, with managers and directors having different perceptions of leadership actions, questioning attitudes, feedback loops, and nonpunitive responses than staff technologists. Therefore, radiologic technologist subgroups must be included purposefully in the process of establishing a radiation safety culture in the imaging department.
