Dental Radiation Health: Safety and Protection in the Digital Age, 2nd edition


About the Course 
Radiation safety remains a top concern for the general public, and the dental professional needs to stay up to date on the latest research and current thinking on radiation safety and protection. This basic-level course reviews the biologic effects of radiation, the methods used in radiation measurement, and the potential sources of radiation exposure. This course discusses radiation safety and protection measures for both patients and dental healthcare workers. Perhaps most important, this course prepares all dental professionals – including dentists, dental hygienists, and dental assistants – to accurately respond to patient questions and concerns about radiation safety in dentistry.
