Statistical analysis defines dual lower detection limits for radioactivity counters, highlighting the critical distinction between measured thresholds and true sample activity.

Key Points

To establish rigorous statistical definitions and derivations for the lower limit of detection in radioactivity counters based on acceptable risks of decision errors.
Formulated mathematical detection limits based on maximal acceptable risks of Type I errors (false positives) and Type II errors (false negatives).
Differentiated theoretical criteria governing observed detector signals versus the true underlying radioactivity present within a sample.
Defined 'minimum significant measured activity' as the lowest instrument reading indicating that sample activity is statistically greater than zero.
Defined 'minimum detectable true activity' as the minimum true radioactivity required in a sample to ensure detection with a predetermined level of statistical confidence.
