Abstract

Abstract In a radioactivity-distribution detector, an array of light conduits in spaced relation to a plurality of visible light emitters defining a grid network is provided for identifying and specifying the location of an active or light generating emitter. The conduits are disposed in a plurality of row pairs, the first of the pair being in bisecting staggered spaced relation to the second of the pair. Specific ones of the light emitters are in exclusive spatial relationship with selected ones of the light conduits and other ones of the light emitters are in spatial relationship with a specified combination of light conduits, whereby each emitter is identified by either a single light conduit or a unique combination of light conduits.
