[ RadSafe ] Air Sample Handling

[Robert Atkinson]

Hi,
Why don't you consider the conductive plastic anti-static bags designed
for electronic components? For example, <

Ntt=anti-static+bag&Ntx=&_requestid=23922 >
The black ones are bulk conductive and should be better for this
application than the silver (buried layer) type. Even the cheap pink
(static resistant) ones would be a big improvement over a standard
Ziploc.

Robert Atkinson.

Subject: [ RadSafe ] Air Sample Handling

I am weighing options for handling high volume air particulate samples
(4in and 8x10" )in the field.

Currently we use commercial plastic bags (ziplock) to preserve the
sample during handling and shipping to an analytical laboratory.  We are
considering using an inner envelope of glassine to reduce the quantity
of material dislodged from the filter paper during sample handling.

I am not sure that glassine has significantly less static electricity
buildup than the plastic bags themselves and would like opions as well
as any emperical data to support a specific filter handling regime.
