WitrynaThe HVL required to shield against high energy photons from brachy- therapy sources is several millimetres of lead. For low energy photons the required thickness is much smaller, usually less than 0.1 mm of lead. 13.2.2. Physical characteristics of some photon emitting brachytherapy sources WitrynaHVL (Half Value Layer): The amount (thickness) of a given shielding material needed to reduce the radiation emissivity by one-half its value. We use the following math …

A material's half-value layer (HVL), or half-value thickness, is the thickness of the material at which the intensity of radiation entering it is reduced by one half. HVL can also be expressed in terms of air kerma rate (AKR), rather than intensity: the half-value layer is the thickness of specified material that, "attenuates the beam of radiation to an extent such that the AKR is reduced to one-half of its original value. In this definition the contribution of all scattered radiation, other than an… diane bish videos
