Introduction to Dosimetry

Introduction to Dosimetry

by Richard Sparks, PhD, Jeff Siegel, PhD

This course is appropriate for those who have little to no knowledge of dosimetry or the basic underlying concepts such as production of radiation, interaction of radiation with tissues, etc. It is also appropriate for someone who wishes to review the basic concepts of radiation and radiation dosimetry. Those completing the on-line exam will receive a certificate of completion.
