Re: Self-Absorption Effects on Air Filters

[Jeff Whicker <jjwhicker@lanl.gov>]

Elizabeth,

As you might have surmised by now, this is not always a simple problem.  A
paper that helps explain some of the complexities of this problem is :

Moore, M.E., McFarland, A.R., Rodgers, J.C.  Factors that affect alpha
particle detection in continuous air monitor applications.  Health Physics,
Vol. 65(1):69-81; 1993.

Best regards,
