2. (12 pоints)The figure belоw illustrаtes а situаtiоn in which 1 MeV photons from a distant point source are collimated to become a narrow beam just covering the detector and pass through three distinct attenuating slabs each with the same thickness (t) before they hit the detector. Assume everywhere except the collimators and attenuators are filled with air in the figure. Do not type response to this question into Canvas - simply type "see Scratch Paper" into response box. a) (2 points) If the detector sees both primary and secondary photons, how would you classify the beam geometry? b) (3 points) Would it be possible to make the detector see only primary photons? If so, how? c) (4 points) Suppose the detector is capable of counting only primary photons. Measurements with this detector suggest that the initial photon fluence is dropped by half after the passage of photons through the attenuators. If the thickness of each attenuating slab is t=1 cm, what is the value of the linear attenuation coefficient for the slab medium at 1 MeV? d) (3 points) If the values of kerma and collision kerma in an air-filled detector are 1.0cGy and 0.8cGy, what is the ratio between the energy transfer coefficient (utr) and the energy absorption coefficient (uen)? Assume a constant energy fluence.
