Abstract

This paper extends previous work for decision levels to detection limits. After transforming the net count to an integer, the probability density function for the transformed net count can be readily determined when the transformed net count is greater than zero. The right tail of the distribution is summed and the detection limit is determined to four decimal places. The code under discussion works well when the product of the ratio of the blank count time to the sample count time with the expected blank count in the sample count time is not greater than 100.0.
