Charles Davis, visiting associate professor at UNLV and EnviroStat, will be the featured speaker at a Department of Mathematical Sciences statistics seminar.
His talk is titled, "One Statistician’s Thoughts on Using Metal Ratios to Distinguish Between Naturally Occurring and Anthropogenic Beryllium in the Workplace."
Refreshment starts at 10:45 a.m. Everyone is welcome.
Abstract: Metal ratios can effectively predict the amount of (non-toxic) natural beryllium (N-Be) that should be found in an inside-facility sample based on the amounts present of other metals characteristic of minerals in background soils. The difference between the total Be measurement and the predicted N-Be for that sample is an estimate of the amount of (toxic) anthropogenic Be (A-Be) present. These A-Be estimates can then be used in determining whether the facility is “clean” using an appropriate decision rule.
