NPRE 441: Principles of
Radiation Protection
Spring, 2025
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.
