Abstract
PURPOSE:To perform two kinds of radiation measurements with one PM system and a pulse amplifier system by measuring the intesities of the two or more kinds of radiations by using one photomultiplier tube (PM) and one pulse amplifier system. CONSTITUTION:An NaI scintillator 1 and a plastic scintillator 2 are formed in a disk shape, respectively. Both scintillators are coupled in the stacked state in two stages. Thus, a series coupling type scintillator 3 is constituted. The NaI scintillator 1 receives gamma rays and emits scintillation light. The scintillation light is inputted into a photomultiplier tube PM 4 through the plastic scintillator 2. Meanwhile, the plastic scintillator 2 receives neutron rays and the gamma rays and emits scintillation light. The scintillation light is inputted into the PM 4. In this way, the detected signal component of the gamma rays from the NaI scintillator 1 and the detected signal component of the neutron rays from the plastic scintillator can be taken out in a separated pattern.

System for determining the type of nuclear radiation from detector output pulse shape

TL;DR: In this paper, a radiation detection system determines the type of nuclear radiation received in a detector by producing a correlation value representative of the statistical cross correlation between the shape of the detector signal and pulse shape data previously stored in memory and characteristic of respective types of radiation.
