Abstract

The possibility of decreasing the depth-dose inhomogeneity in polyethylene with double-sided and one-sided electron irradiation at diﬀerent angles with a maximum eﬃciency of beam use is investigated. The least squares method was used to determine the optimal parameters, the thickness of the object, and the fraction of the beam incident on the object at angles Θ = 0◦ and Θ ≠ 0◦. When irradiating with a main beam with an angle Θ = 0◦ and an additional one with Θ = 70◦, it was shown that at an eﬃciency of ≈ 97%, the technique allows reducing the deposited dose inhomogeneity in objects from 70, 51 and 38% to ∼17%, and with ﬁlters from Al (eﬃciency ≈94%) to 5% for electron energies of 2,5, and 9MeV respectively.
