NPRE 441: Principles of Radiation Protection

Spring, 2008

 

 

Course Description

This course covers the following topics: sources of nuclear radiation; ionization and energy deposition in matter; basic tools for radiation detection and measurements; principles of dosimetry; determination of exposure and limits for internal and external emitters; basic shielding calculations. The course is designed to provide students with a comprehensive background in the basic physical and biological factors governing radiation effects and with practical means for assessing and controlling the radiation doses expected from various radiation fields.
