Course Description
As the use of diagnostic imaging has increased, so has interest in and scrutiny of ionizing radiation dose exposure and its effect on patients and radiographers. Concern about the overuse or unsafe use of ionizing radiation exists, because it has the ability to rearrange the molecular structure of the body parts it passes through. This can cause both chemical and biological changes, making it important to explore techniques that limit exposure and protect radiosensitive organs. This article discusses the hazards associated with ionizing radiation and currently available protective devices for patients and radiographers, as well as actions being taken by various organizations and societies to further address radiation safety issues.

Learning Objectives
After reading this article, the participant should be able to:

• Identify the hazards associated with ionizing radiation in medical radiography.
• Discuss current radiation protection devices used to limit exposure to ionizing radiation in medical radiography for both the patient and radiographer.
• Examine the changes that have occurred in radiation safety since the transition to digital radiography.
• Describe what actions are being taken by professional societies, accrediting organizations, and regulatory bodies to address radiation safety issues.
