Filter Collection Efficiency for Personal Air Monitor (PAM/Lapel) Samples

["Redmond, Randy R. (RXQ) " <RXQ@ornl.gov>]

Can anyone point me in the right direction for data on the filter collection
efficiencies for Millipore, AW-19, and Whatman-41 filters when used at low
flows, e.g., 2 to 3 lpm?  

Additionally, any alpha self-absorption information (for the various filter
types) for samples used in actual airborne radioactive material environments
would be very useful.

As usual, everyone's help is appreciated.
