WebThe thickness of any given material where 50% of the incident energy has been attenuated is know as the half-value layer (HVL). The HVL is expressed in units of distance (mm or cm). Like the attenuation coefficient, it is photon energy dependent. WebFor the photons used for medical X-rays, the half thickness for lead is about 0.5 millimetre. However, photons with energy five times as high have a half thickness of 10 millimetre of lead, or 50 mm of concrete. Start with 1 024 000 high-energy photons. After 50 mm of concrete there will be 512 000 photons.
