Efektivitas Tungsten sebagai perisai radiasi foton

Tungsten is a material that has a high density and atomic number which is a potential candidate for photon shielding. In this study, Tungsten material with a thickness of 10 cm was used as a shield for photon with energies of 2 MeV, 3.3 MeV, and 5 MeV. This material shielding was simulated with Monte Carlo based software, Particle and Heavy Ion Transport System (PHITS). The dimensions of the shield material are 40×40×10 cm3 which are placed at various distances from the source:20 cm, 50 cm, and 100 cm. The results obtained show that these photons with energies of 2, 3.3, and 5 MeV can be attenuated by the shield at all defined source distances. The flux of particles passing through the shield decreases with increasing distance. Therefore, Tungsten material can be a candidate for photon shielding in the medical physics field.
