COUNTING-LOSS AND PILE-UP OF PULSES FOR PULSED X-RAY COUNTING

Counting loss in dose-rating with a pulse detector is discussed, and the relation of counting loss to average dose rate is clarified. The relation of counting rate to pile-up of pulses in measuring pulsed x-ray spectra is also discussed and a formula is derived for calculating the ratio of the number of signal pulses with no pile-up to that of total signal pulses.
