How is radiation distributed in this experimental setup

Click For Summary
SUMMARY

The discussion focuses on the spatial and energetic distribution of radiation from an X-ray tube striking a fluorescent plate. The X-ray tube emits rays at a large angle of over 100 degrees, leading to a spherical distribution of fluorescent X-rays from the point of incident radiation. The conversation highlights the uncertainty regarding the propagation of rays from the source and the energy deposition at various distances from the incident point. Geant4, a simulation toolkit, is recommended for further exploration of these radiation distribution questions.

As shown, an X-ray tube (source) is striking a fluorescent plate.

The source has a large angle (100+) that the rays are emitted.

How is radiation distributed (spatially and energetically) in this set up? Does this differ from other type of distribution produced by other types of radiation?

My thoughts are that the fluorescent X-rays produced from the plate material are distributed from the site of incident radiation in a spherical distribution.

However some things I am unsure of:

How the rays propagate from the source. Do they bounce of the shield and get directed towards the plate?

Would as much energy be deposited at any location located a distance r away from the point where the rays from the source are incident on the plate? As long as this location is not behind the plate?
