Radiation Dosimetry Friday, December 2 12:30 PM PHYS 331 Matt Kay Abstract Radiation is ubiquitous. Whether it is the sun beating down our backs or the dentists searching for cavities we are constantly being bombarded by radiation. The effects of radiation on the body can range from the immeasurable to changes in blood chemistry to nausea to even death. For this reason, a basic understanding of radiation dosimetry is beneficial. Nuclear physics and the technologies that arise from it are playing an ever increasing role in today’s society with respect to the generation of electrical power, medical treatments, nuclear weapons proliferation, and the “dirty bombs” of terrorists. An important aspect of all these topics and one that at times is not often talked about in a quantitative sense is risk. Understanding risk and being able to quantify it is an important topic when discussing radiation dosimetry. In this talk, the basic terminology and conventions used in radiation dosimetry will be covered. The biological effects of radiation will also be presented. Background radiation and what is considered to be the average dose rate for the general public will be discussed. The talk will conclude with a brief discussion on the evaluation and interpretation of risks. Biography Matt Kay is currently a graduate student in the Physics Department at Purdue University. He received his B. A. at Wabash College and M.S. in Physics at Purdue. He is currently a Research Assistant at the Applied Physics Laboratory at Purdue. He is studying materials classification and identification using neutron-induced gamma ray spectroscopy.
