1. The point P at the origin of a spherical-surface radiation source. The diameter of the sphere is 30cm, and the source intensity is uniform of 10^5 particles cm^-2 sec^-1 over the entire spherical surface. (a) Calculate the fluence rate (particles cm^-2 sec^-1) at P. (b) Calculate the average fluence rate over the entire sphere. (NOTE: Medium is a vacuum).
2. Professor says we should use a probability cord density to solve, i think, part b. I don't know how to approach part a or b, but below is my thinking
3. Should i take the source intensity and integrate it over the surface of the sphere using a double integral? This has been my best idea, but am unsure what to set the limits of integration to. I will show my attempt now, despite my shame.
