Question

Find the approximate solid angle for a source-detector arrangement whereby a 5-cm diameter
detector is placed 30-cm from a point source which emits gammas isotropically. Formally, one
would find a solid angle by integrating sinθ dθ dφ over appropriate θ and φ limits given by the
size of the detector at the given distance from the source. However, a good approximation is to
use the ratio of the detector area to the surface area of a sphere at the detector distance to find
the fraction of 4-pi which the detector covers
