RE: Peanut butter or other skin decon methods in place of water and soap
George,
As you point out, until now decontamination agents have been non specific.
About a month ago we introduced Iodowash specifically for cleanup of
radioactive
halogens both on in-animate objects and skin. We continue to receive
testimonials
and praise for how well it works. Since that time we have introduced
Thallium
wash, Technetium wash (which is already on back order), Cesium - Cobalt
wash,
and Uranium wash. All are mild enough to use on intact skin.
The washes contain a specific (for each group of elements) solution which
frees the element from the surface. The wash also contains a resin bead
designed to bind the element. The bead can easily be removed from the
surface
and disposed of as radioactive waste. These washes have been used
effectively
on tile, linoleum, painted surfaces, stainless steel, leather, skin, etc.
Due to the specific nature of these washes, there are occasions where they
are not 100% effective. The use of some cleaning products can build up
residues on the surface to be cleaned which either react with the solution
or saturate the resin. A pre wash with de-ionized water has been very
successful in providing a surface on which the ion specific washes can be
effective.
My apologies for sounding like a commercial.

Paul,
Having been involved in writing several different personnel decontamination
procedures, it is important to understand both the chemical and physical
characteristics of the potential contaminant and design procedures that are
effective in removing the offending agent as well as maintaining the skin
barrier intact.
For example, chelating agents such as EDTA are wonderful for removing
transition metals (e.g., Co, Mn), but are completely ineffective for
halogens such as I. Cs can be complexed and removed with agents such as
Prussian Blue (aka "Radiogardase"). If you have any chemical and physical
data on the nature of your potential contaminants, contact me off-line and
we can discuss.

Fellow RadSafers -
I've heard from some of our RCTs about using peanut butter as a decon
method for skin contamination, particularly for Tc-99 removal. Why does
peanut butter work so well, other than it's sticky? What other
alternatives to using lukewarm water and mild soap have y'all used
successfully?
Thanks -
