Abstract

This paper presents a novel method for making an inexpensive, low resolution, wide angle gamma-ray camera using a single handheld inorganic scintillation detector. A lead aperture is used to create a directionally sensitive detector and craterisation points are measured and compiled into a pixelated spherical gamma-ray image. The gamma-ray image is separated into energy channels and overlaid on top of a grey scale visual panoramic image so that collared pixels indicate the position and energy of gamma-ray sources.
