Subject: Projection of isotropic 3D radiation on flat screen
Hi,

When I have an isotropic point-like source that radiates isotropically in 3-D space, how can I calculate the number of events that reach a screen a

certain distance away, with the probability as a function of (transversal) x and/or y on that screen.

Hence, I want to know how to derive a function for the amount of events that reach a certain region on a flat screen, when the origin of these events is some isotropic point-like source.

Any help would very much be appreciated.

Best regards,

Machiel
