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

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.
