Abstract
A radiation analyzer which employs a single photodetector and a plurality of scintillators. Light filters interposed between selected ones of the scintillators selectively attenuate radiation of a predetermined energy range. Plural analyzers each associated with a single scintillator and each receiving electrical pulses from the photodetector attenuated to a different degree are adjusted to tabulate pulses of amplitudes which differ in accordance with the degree of attenuation of pulses received by the analyzers from the photodetector.
