Abstract :
This paper describes a technique for determining the interaction radius of a gamma ray within a cylindrical detector. This can be useful information for correcting pulse amplitudes and selecting events of interest. A theoretical expression for the event radius is derived based on anode signals, and simulations are compared with experimental results.
