1. A method of improving energy determination of a Gamma particle which interacts with a segmented scintillation detector, the method comprising:
- identifying gamma particles detected by the detector that are likely not to have deposited their full energy in the detector, based only on characteristics of said detected events; and
treating the identified radiation gamma particles differently from other radiation events that are likely to have deposited their full energy in the detector.

40. A method of discriminating a Gamma event which interacts with a segmented scintillation detector from nuclear particles which interact with the segmented scintillation detector, the method comprising:
-
determining a number of detector segments within scintillations are generated as a result of an incoming particle; determining the shape of the scintillations generated; provisionally classifying the incoming particle as a gamma particle based on the number of detector segments and the shape of the scintillations; identifying incoming provisionally classified particles whose scintillation characteristics indicate that they have not deposited all of their energy in the detector by one or both of;
(a) the distance of a final scintillation associated with or resulting from a given gamma particle from a boundary of the detector; and
(d) the time duration of a series of scintillations resulting from an gamma particle. - View Dependent Claims (41)
