Abstract
A method for reducing the background count rate in radioactivity measurements with a coincidence-anticoincidence evaluation, in which pulses from a detector and pulses from a shield counter device are amplified and compared based on a time relationship, reduces the zero sample counter rate of the detector by supplying the amplified pulses to analog/digital converters which convert the pulses to digital values at a predetermined clock frequency. When a detection pulse is identified, digital values are transferred to a PC system. In the PC system the height, shape, or slope of the detector pulses is compared to the height, shape, or slope of any contemporaneous pulse from the shield counter device. Circuitry for performing the method is also disclosed.
