WebThe major advantage of the lead shield is its compactness due to its higher density. On the other hand, ... If we want to account for the buildup of secondary radiation, then we have to include the buildup factor. The buildup factor is then a multiplicative factor that accounts for the response to the un-collided photons to include the ... WebThis configuration is a significant departure from the infinite medium which is assumed when determining the buildup factors, especially in the case of a heavy-element shield such as lead. Therefore, a table of correction factors are …
WebAn empirical formula for gamma-ray buildup factors in two-layer shields is proposed. The values of the parameters are given for the formula when fitted to the dose buildup factors, calculated by the invariant imbedding method, for normally incident gamma rays penetrating two-layer shields comprised of combinations of water, iron, or lead slabs.
