title: Improved derivation of results of D. E. Allen: two-count method for stripping short-lived activity out of an air sample.
abstract: An improved derivation of the critical levels and detection limits for a two-count method that attempts to measure long-lived activity in the presence of short-lived, naturally occurring progeny of radon is presented. A limitation of the two-count method is also mentioned.
