Kopp, M K

A radiation dose-rate meter is described comprising: an energy-sensitive radiation detecting element which generates at an output thereof ionization current pulses having an amplitude proportional to the charge quanta deposited in the radiation detecting element by detected photons of ionizing radiation; a charge-sensitive preamplifier connected to the output of the radiation detecting element; a filter amplifier having a selected filter time constant for generating fixed width pulses at an output thereof in response to each of the step voltage pulses from the preamplifier having an amplitude proportional to the amplitude of each of the step voltage pulses applied to an input thereof; a multi-level discriminator means responsive to the voltage pulses at the output of the filter amplifier for generating a train of count pulses at an output thereof in response to each of the fixed width pulses; and a count rate meter means connected to the output of the multi-level discriminator means of registering the count pulses of each of the train of count pulses as a quantized measure of the radiation dose-rate per unit time of the detected photons of ionizing radiation.
