REQUEST FOR INFORMATION

Is anyone aware of any documented technical basis for performing large area
wipes for alpha contamination, particularly using an oil-impregnated smear
media, such as Masslin cloth?  The discussion should consider dust loading,
self-shielding by the oil, collection efficiency, and minimum detectable
activity.  I am particularly interested in a study that is documented to the
level it can be used as a reference.

Thanks,
