Physics 576 Fall 2019
Radiation: Sources, Detectors and Safety
Garcia: to be announced;
NPL conference room
This is a class on Radiation: Sources, Detection, and Safety. Students will learn some basic concepts on nuclear physics; the processes that can produce radioactivity and to recognize dangerous versus safe environments; practical experience with high-resolution photon detectors; the basics of particle accelerators and practical experience with our own tadem accelerator; the basics of Rutherford scattering and how it can be used to identify minute amounts of contaminants; the basics of the functioning of nuclear reactors; and some concepts on nuclear astrophysics.
I hope you find this course stimulating and interesting.
I will expect you to read the material that will be covered in a class ahead of time. I expect students to ask on average one question per class. Students will ask the question during lecture and will then send an electronic note to the instructor to register the question. The questions will be posted by the instructor anonymously but so that others may have a reminder of what issues were considered.
