The Alliance for Radiation Safety in Pediatric Imaging is an organization of over 45 international professional societies and agencies with the goal of promoting radiation safety for children. The Alliance, through the Image Gently campaign, uses social marketing techniques and critical partnerships with vendors, government agencies, and not-for-profit organizations, to advocate best practices in radiation use and safety. Advocacies include improving education regarding radiation risk to patients from medical imaging for radiologists, technologists, and referring physicians; promoting standardization of dose measurements and display across vendor equipment; and improving medical literacy for parents.
