Nuclear Radiation Physics
This is a survey course in nuclear radiation physics. Topics to include atomic and nuclear structure, radioactivity, nuclear reactions, interactions of radiation with matter, dosimetry, particle and radiation detection devices,accelerators, neutron physics, fission and fusion, cosmic rays and transuranium elements. Examples of radiation absorption in both inorganic and biological systems will be discussed.
Prerequisite: Modern Physics
GOALS AND OBJECTIVES
(Knowledge and Skill Objectives):
This course is intended as a summer term survey course in Nuclear Radiation Physics. The course is designed to familiarize students with the field ofnuclear physics, emphasizing an experimental physicist's point of view. There is emphasis on radioactivity, emission and absorption of radiation and dosimetry. Also emphasis on a broad knowledge of accelerators and particle detectors for pursuit of further graduate studies in physics or work in industry or medical physics field.

CALENDAR:
The course calendar is driven by the above course content. Content areas will generally be in the order shown above. Some topics and related applications may require more time than others; the listed content, however, is entirely covered. The instructor is required to administer graded work (homework, quizzes, tests, and examinations) whose cumulative substance is congruent with the scope and depth of the above content and the taxonomy of the cognitive domain. An average of at least one graded assignment per week is to be expected, along with mid-term and final examinations.
