Swab Conversions

[David Biela <bielad@wv.doe.gov>]

1.  Has anyone performed any test converting dpm on a swab (small wad of 
cotton on a stick) used for example inside a pipe to dpm/100cm-sq?  What are 
your ideas on determining the area of the swabbed section in a pipe when you 
are taking it through a small drilled hole? 

2.  Is there any data out there that estimates the amount of expected airborne 
activity when welding or cutting a pipe with internal and/or external 
contamination.

Please send any comments to me at BielaD@wv.doe.gov

Thanks
