Abstract:
|
An experimental design was developed to assess sampling strategies and methods for (i) detecting contamination in a building and (ii) clearing the building for use after decontamination. An unoccupied building was contaminated with a Bacillus anthracis simulant. The experimental design planned several contamination events, with sampling, decontamination, and re-sampling for each. The first objective was to assess the abilities of judgmental and probabilistic sampling strategies to detect contamination. The second objective was to assess the use of a probabilistic sampling strategy and a Bayesian sampling strategy (which combines judgmental and probabilistic samples) to make clearance statements of the form "X% confidence that at least Y% of an area does not contain detectable contamination." The presentation gives an overview of the experimental design and sampling plans selected.
