NPRE 441: Principles of Radiation Protection

Spring, 2023

 

Course Description

This course provides a comprehensive coverage of the principles and methodologies underlying radiation protection and radiation health physics. The major topics being discussed in this course include sources of ionizing radiation, the interaction of ionizing radiation with matter, essential tools and techniques for dosimetry measurements, counting statistics, principles of radiation dosimetry, biological effects of ionizing radiation, methods for deriving the radiation dose from internal and external radiation sources, and standard approaches for shielding design and radiation protection.
