Determination of the Tenth and Half Value Layer Thickness of Concretes with Different Densities
Acta Physica Polonica A, 2016 Half value layer (HVL) is the most frequently used quantitative factor for describing both the penetrating ability of specific radiations and the penetration through specific objects. The half value layers (HVL) and tenth value layers (TVL) are defined as the thickness of a shield or an absorber that reduces the radiation level by a factor of one-half ...
