Radiation safety and protection

Course Description: This course presents the scientific principles and regulatory framework for radiation safety and protection in the medical environment. It covers the physical quantities and units used to describe radiation dose, the biological basis of radiation risk, and the system of radiation protection based on the principles of justification and optimization (ALARA) and dose limitation. It also addresses practical protective measures applied to patients, workers, and the public in diagnostic and interventional imaging, including time, distance, and shielding, protective equipment, personal dose monitoring, and compliance with national and international radiation protection legislation.
Credits: 2
Prerequisites: RAD 221
Objectives of the course :

• Definition of fundamental quantities and units of radiation dose (exposure, air kerma, absorbed dose, equivalent dose, and effective dose) and performing related calculations.
• Explain the biological effects of ionizing radiation and differentiate between deterministic and stochastic effects.
• Application of basic principles of radiation protection: justification, optimization (ALARA), and dose limitation.
Utilize time, distance, and shielding to minimize dose to patients, workers, and the public.
• Description of personal dosimetry and radiation measuring devices and the adjustment of classified areas.
Identifying national and international legislation, standards, and regulatory bodies governing radiation safety.

Course outputs :

• Description of quantities and physical units used to express radiation dose and sources of radiation exposure.
• Explanation of the biological basis of radiation hazard and the principles of the radiation protection system.
Skills
• Applying time, distance, and shielding, and performing dose and dose rate calculations to minimize exposure to patients, workers, and the public.
• Use of radiation monitoring devices and personal dosimeters to assess occupational and patient exposure.
Values
• Adherence to practices within national and international legislation for radiation protection and the ethical boundaries of the profession.
• Distinguishing between radiation dosimetry units and their related calculations and benefits.
