[Gate-users] LSO and LYSO intrinsic activity simulation

[Bryan McIntosh]

That peak is the peak of the beta spectrum that you're seeing. Because
you're viewing the singles data, you'll always see the beta and gamma
events in your crystal volume. By running in coincidence mode, your
spectrum should look more like what you find in my thesis.
