Lead that has been employed widely for shielding in electron beam radiotherapy can produce bremsstrahlung photons during the shielding process. A novel shielding scheme with a two-layer structure has been studied using a Monte Carlo method in order to reduce this bremsstrahlung effect. Compared with the conventional lead, the novel shielding scheme, comprised of a Styrene-Ethylene-Butylene-Styrene Block Co-polymer (SEBS) above and lead below, can efficiently reduce the generation of bremsstrahlung while providing better shielding for incident electrons. Therefore, this novel shielding scheme may play an important role in future applications.
