Ultra high purity aluminum has proven to provide more accurate measures of half value layer in mammography than
aluminum alloys. While the aluminum supplied in the 115A is appropriate for testing non-mammographic systems, it is
insufficiently pure for accurate testing of mammographic systems
Model Number:Model 115H GOLDWEI Item No.:UPGX-115H
Ultra high purity aluminum has proven to provide more accurate measures
of half value layer in mammography than
aluminum alloys. While the aluminum supplied in the 115A is appropriate for testing non-mammographic systems, it is
insufficiently pure for accurate testing of mammographic systems. The Gammex 115H Half Value Layer Attenuator Set
provides the needed substrate purity for accurate MQSA HVL compliance. The set consists of six 10x10x0.1 mm sheets of
99.99% pure aluminum, and includes a plastic storage case to protect and help maintain flatness of the filters.
