[Gate-users] Photon's energy and direction

[Suhaili Zakaria]

Hi all

I am hoping someone could help me in this:

I have a Y90-beta source (pure beta emitter) in a water phantom.
I need to know where the bremsstrahlung photons are produced in the water
phantom, its energy and direction. I want to find out the offset of the
photons from the source position.
How can I obtain this information?

Really appreciate your reply.
Many thanks,
S
