Justification of Shielding Requirements for Plutonium Sources
Leticia S. Pibida, Michael P. Unterweger
This report provides a justification for shielding plutonium sources when testing radiation detection instruments against standard performance requirements and test methods. The use of copper as a shielding material is proposed to provide comparable test results when testing radiation detection instruments in different location using different plutonium sources with varying 241Am content.
