Introduction Radiation safety is a fundamental requirement in healthcare institutions that use ionizing radiation for diagnosis and treatment. Medical imaging, computed tomography, fluoroscopy, nuclear medicine, and radiotherapy provide great clinical benefits, but they must be used carefully to protect patients, healthcare workers, and visitors from unnecessary exposure.

Concept of Radiation Safety Radiation safety refers to the procedures, standards, and protective measures used to minimize exposure to ionizing radiation while maintaining the required diagnostic or therapeutic benefit. One of the most important principles in this field is ALARA, which means keeping radiation doses “As Low As Reasonably Achievable” without compromising the quality of medical care. Sources of Radiation in Healthcare Facilities Radiation sources are commonly found in X-ray rooms, computed tomography units, fluoroscopy suites, nuclear medicine departments, and radiotherapy centers. The level of risk depends on several factors, including the type of radiation, exposure time, distance from the source, and the availability of proper shielding.

Basic Principles of Radiation Protection Radiation protection is based on three main principles: time, distance, and shielding. Reducing the time spent near a radiation source lowers the received dose. Increasing the distance from the source also reduces exposure. Shielding, such as lead barriers, protective walls, lead aprons, and thyroid shields, provides an additional layer of protection. Role of Healthcare Workers Healthcare workers have a key role in maintaining radiation safety. They must ensure that each radiological procedure is medically justified, select the appropriate imaging protocol, adjust exposure settings according to the patient’s condition, and use personal protective equipment when needed. Staff members who work regularly with radiation should also wear personal dosimeters to monitor occupational exposure.

Patient Safety Radiation safety does not mean avoiding radiation completely; rather, it means using it only when clinically necessary and in the safest possible way. Each examination should have a clear medical indication, and lower-dose alternatives should be considered when appropriate. Special attention should be given to children and pregnant patients because some groups may be more sensitive to radiation effects. Risk Management and Training Healthcare institutions should establish a clear radiation safety program. This program should include staff training, equipment quality control, dose monitoring, incident reporting, and regular evaluation of safety practices. Written protocols should be available in radiology departments, and continuous supervision is necessary to ensure compliance with accepted safety standards. Conclusion Radiation safety is a shared responsibility among healthcare administrators, physicians, medical physicists, radiologic technologists, and other healthcare professionals. Safe use of radiation improves the quality of healthcare services while protecting individuals from unnecessary risks. Promoting a strong culture of radiation protection is therefore essential for safer and more effective healthcare environments. Al-Mustaqbal University, the First University in Iraq
