Recent advances in instrumentation provide the capability to measure s
ize, count rate, type of radiation, and the chemical composition of ra
dioactive particles. We present a demonstration of these capabilities,
using a laser-scanned phosphor imaging system and a charge injection
device system for digital autoradiography, light and electron microsco
py, energy dispersive X-ray spectrometry, and conventional radionuclid
e spectrometry. Response characteristics of the phosphor system that s
upport these efforts are presented. (C) 1998 Elsevier Science Ltd. All
