Abstract:
A method of radiation detection comprising the steps of:a) generating radiation decay rate counts wherein said counts comprise a sum of detection radiation decay evens over a time interval;b) loading said counts into an array;c) summing selected elements of said array to generate a total count and a plurality of candidate counts;d) comparing said total count to one of said candidate counts to determine whether said one of said candidate counts is statistically different from said total count;e) using said statistically different one of said candidate counts as an output count rate;f) generating an output signal using said output count rate to determine the characteristics of said output signal;g) partitioning said plurality of candidate counts into: a last count value at priority 1; a sum of the last two count values at priority 2; a sum of the last four count values at priority 3; a sum of the last eight count values at priority 4; said total count at priority 5; andh) selecting said one said candidate counts as the highest priority count value that is a statistically significant change from priority 5 said total count.
