Product Description

Half Value Layer Attenuator Set

The Gammex 115A Half Value Layer Attenuator Set is designed to be used to determine the Half Value Layer (HVL) of the x-ray beam to specify the quality of the x-ray beam.

For a given kVp, a measurement of the HVL gives information on the total filtration in the x-ray beam.  Too little filtration results in unnecessary radiation to the patient and too high of an HVL may require increased kVp and mAs, increasing tube loading and reducing tube life.


  • Aluminum alloy sheets come in a plastic storage case to help maintain flatness and for ease of storage and transportation
  • Aluminium of sufficient purity to be used for x-ray beam quality determination
  • The set contains 9 sheets of various thicknesses ranging from 0.1 mm to 2.0 mm
  • 99.0% pure aluminium


  • Easy to use and customize in thicknesses for specific tasks
  • Easy to store
  • Economical Compact
