The half-value layer (HVL) is the thickness of material that reduces the intensity of radiation entering it by one-half.


Some medical applications are

  • To determine the thickness of shielding needed to protect X-ray technicians from stray radiation

  • To adjust X-ray intensity to a level appropriate to the diagnostic procedure

  • To shield some areas of the body when other parts are being X-rayed.
