Introduction to radiation safety and monitoring.

Ionizing radiation is used in diagnostic imaging, external-beam radiation therapy, brachytherapy, and nuclear medicine to diagnose and treat a number of common conditions. To ensure the safety of patients, providers, and surrounding staff members, it is important that the health care community become familiar with the terminology, common equipment, and standard practices used in radiation safety and monitoring. The authors aim to provide an introduction to radiation safety and monitoring so that health care providers and support personnel who may have contact with patients, equipment, and facilities that use radioactive material may be more aware of the policies and precautions that are in place to ensure their safety.
