Abstract : Polyethylene samples were exposed to a relatively small (approximately 8.7 curies) cesium-137 gamma source for varying durations of time. The chemical oxidation was measured by infraredABSORPTION TECHNIQUES, AND THE PHYSICAL CHANGES BY MEASUREMENTS OF ELONGATION AND TENSILE STRENGTH. All changes were a direct result of the quantity of radiation received. The results indicate that polyethylene has significant potentiality as a wide range gamma dosimetry material. The polymeric dosimeter has proven to be reasonably accurate in the exposure range of 1 x 10 to the 6th power to 5 x 10 to the 7th power roentgens. (Author)
