Abstract: PURPOSE:To determine a proper averaging time quickly by comparing the sums of counts between adjacent groups while addition elements within the group are increased by geometrical progression and instability is determined when the difference of the sums becomes large to adopt the stable period as averaging period (counting rate computation period). CONSTITUTION:The sum S1 of counts is computed to those at the (2K<-1>-1)th position (wherein K= 0, 1, 2...) retroactive from the current counts and then, the sum S2 of the counts to those at the(2K<-1>-1)th position from the counts at the 2Kth position. Then, the sums S1 and S2 of the counts are compared increasing K and the period when changes in the counts are stable is determined to be a stable period which is used as averaging time to calculate a counting rate. Here, a coefficient C is set and when ¦S1-S2¦ <C is satisfied, the stable period may be defined. The decision of the stable period allows the specifying of the value of K and thus, a counting rate R can be calculated quickly by R=S1(2K.DELTAt), wherein DELTAt represents a sampling time.
