This publication contains guidelines on the proper handling and use of fixed and portable nuclear gauges, and provides background information about radiation for people who use and work around this equipment. It is intended to provide information to gauge licensees for use in their user training programs. Information may be added or deleted to fit their specific training programs as needed.
This booklet is the result of a cooperative effort between the Office of Public Affairs and the Office of Nuclear Material Safety and Safeguards, both of the US Nuclear Regulatory Commission (NRC). This document is largely adapted from the Atomic Energy Control Board of Canada publication "Working Safely with Nuclear Gauges".
