Question: Consider an Anger camera with only one parallel collimator hole. The measured intensity is the energy deposited on the camera per unit time per unit

Consider an Anger camera with only one parallel collimator hole. The measured intensity is the energy deposited on the camera per unit time per unit area. Suppose the hole diameter is d, and a point source with radioactivity of A is at a distance of r from the camera, directly below the hole.

(a) What is the measured intensity?

(b) What is the measured intensity if we double the hole diameter?
