  • Radiameter
    Patent number: 4087692
    Abstract: Apparatus for measuring atomic radiation includes a plurality of solid-state detectors, typically connected in parallel, each detector being selected such that the parallel combination has a desired response characteristic. The detectors are connected to the input of a pre-amplifier/integrator which, in turn, drives a counter via a trigger circuit. The detectors, trigger circuit and pre-amplifier/integrator may advantageously be combined on a single integrated circuit chip.
