Linearization skill example 1 - 9702/42/M/J/16: (a) Explain what is meant by gamma radiation (γ-radiation). #9702s16p42 #Lv2 #A2decayGraphP4 (b) A source of gamma radiation is placed a fixed distance away from a detector and counter, as illustrated in Fig. 13.1. A sheet of lead of thickness x is placed between the source and the detector. The average count rate C, corrected for background, is recorded. This is repeated for different values of x. The variation with thickness x of ln C is shown in Fig. 13.2. The absorption of gamma radiation in lead may be represented by the equation C = C0 e−μx where C0 is the count rate for x = 0 and μ is the linear attenuation (absorption) coefficient. Use Fig. 13.2 to determine the linear attenuation coefficient μ for this gamma radiation in lead #A2attenuationP4 (c) The value of μ calculated in (b) is for gamma radiation in lead.Suggest and explain whether the value of μ for aluminium would be the same, greater or smaller. #A2nuclearPhysics Playlist:    • Ch23 Nuclear Physics | CAIE 9702 A2 Physics   #A2MedicalPhysics Applications Playlist:    • Ch24 Medical Physics | CAIE 9702 A2 Physics   Instagram Pocket Guide (  / etphysics  ) More Resources (https://9702-physics.blogspot.com/) Support us!
