1. In a system for detecting combined neutron and gamma radiation and distinguishing therebetween, the method comprising:

  • a. Providing a detector for a single photomultiplier, which detector includes a first phosphor material which scintillates primarily in response to neutron radiation and a second phosphor material which scintillates primarily in response to gamma radiation,b. Utilizing a distinguishing characteristic of the scintillations of said first and second phosphors to produce a signal in response to scintillations of one of said phosphors andc. Manipulating an output selection means into which an output of the photomultiplier has been introduced as an input by said signal to produce an output from said output selection means corresponding to the scintillations of said one phosphor.
