Ultra-High Purity HVL Attenuators
Permit accurate half-value layer determinations
Because type-1100 aluminum in only 99.0% pure, it has some impurities that can give an HVL value which is lower than those measured with pure aluminum. When doing HVL measurements with a mammography unit, it is recommended that the highest purity aluminum be used. This set of five attenuators satisfies this recommendation because they are 99.99% pure.
