RESUMO
The relative percent dose reduction of different electron energies [5, 9 and 13 Mev] were measured using Mevatron 74 Linear accelerator and different shielding materials [lead, aluminium, copper and stainless steel]. A step wedge of each was used during this wrk, the steps thickness ranged between 2 mm and 20 mm. It was found that 95% attenuation for energies [5, 9 and 13 Mev] were obtained by 2, 4 and 6 mm thickness of lead respectively compared to the attenuation obtained by other materials of the same tickness
