Question 1 A Parallel Beam Of 2 Mev Photons Is Normally Incident On A Slab Of Material The Thickness Of The Material Is 1 (38.94 KiB) Viewed 40 times

Question 1 A parallel beam of 2-MeV photons is normally incident on a slab of material. The thickness of the material is 1.5 cm and its density is 3.5 g cm'. The rate at which the beam is incident on the slab is 1500 photons/sec. i) ii) iii) iv) v) what fraction of the photons is transmitted without interacting? what fraction of the incident photon energy that is transmitted by the slab? how much energy is absorbed per second by the slab? what fraction of the transmitted energy carried by the uncollided photons? what fraction of the initial kinetic energy transferred to the electrons in the slab is emitted as bremsstrahlung. Assume that for this photon energy and material: u = 0.0692 cm /g (mass attenuation coefficient р hv = 0.0349 cm-/g (mass energy-transfer coefficient P Men = 0.0346 cm²/g (mass energy-absorption coefficient) P
