Abstract
The broad-beam and narrow-beam attenuation of Co60 gamma rays was investigated experimentally. In protective barriers the geometry necessarily requires the use of broad-beam attenuation curves to determine the required barrier thickness. This paper presents attenuation curves for lead, concrete and steel necessary for determining the required protection for any particular Co source in storage or transportation. There is also included a table for shielding requirements for Co60 sources of 10 millicuries to 2 curies.This publication has 1 reference indexed in Scilit:
