A Method of Pulse Integration Using the Binary Scaling Unit

Abstract

In some cases it is desirable to determine the dose resulting from certain types of ionizing radiation by weighting the pulses produced in a proportional counter by their height. An instrument that automatically integrates pulses in such a fashion is described. The pulses actuate one or more of a series of discriminators which are biased at successively higher voltages. The discriminators are connected into successive stages of two binary scaling units in such a way that the total number of counts recorded is proportional to the height of the initial pulse.
