Popis:	Several applications of live‐timer count correction are discussed with regard to the precision and statistical accuracy of results obtained. The method is compared to conventional real‐time operation with subsequent formula correction. For straightforward high‐precision counting, the live‐timer method is believed to be superior. Counting of sources which decay appreciably during the count, sometimes thought to be a case where automatic live‐timer correction fails, can be accomplished by choosing a certain readily calculable ratio of clock inhibit duration to paralysis. Similarly, coincidence counting with different channel paralyses is found to be amenable to live‐timer correction, with a resulting precision which exceeds that of formula corrections.
