Re:Alpha shielding in "Masslin"

[Rodney Bauman <rodney_bauman@wssrap-host.wssrap.com>]

Mike and all interested,

We use masslin wipes for large area alpha contamination surveys in areas
normally free of removable contamination.

I have a copy of a LMES document dated 2/11/97, entitled "Technical Basis for
Alpha Attenuation in Large-Area Wipes: A comparison of Media (Masslin vs. Paper
Towel)."  It has a document control number of RCO/TBD-012, Rev. 0.

As far as I can tell, this document forms the basis for masslin use at the K-25
and Y-12 sites.

I could fax you a copy if you'd like.

BTW, the "not-so-good" financial status of USEC made the front page of the St.
Louis Post Dispatch today.

Hello Radsafers,

Has anyone evaluated the use of masslin in areas of alpha removable
contamination?

I'm looking for data to prove that the oil and fibers on the masslin cloth
will not shield the alphas from a portable survey instrument.  I'll collect
it myself if I have to, but I'm hoping one of you can save me the legwork. 

If you're at a facility where alpha contamination is a concern, do you use
masslin? Why? Why not?
