S-35 Volatility

["Joseph P. Ring" <joseph_ring@harvard.edu>]

The largest issue with S-35 volatility is incubation or autocalving.  There
is some possibility of release/volatility when opening a stock bottle.
Primarily this is for products that are at or over the chemical expiration
date  due to decay of the chemical compound.  There is also some potential
for a newly opened package to have a pressure build-up due to radiolytic
decay.  This 'release' may be a small fraction of one percent of the bottle
contents. 

We have had occassion to do monitoring in a S-35 use lab that has low
ceilings (8 foot) that also is where the autoclaving is done.  These
measurements indicate that there may be some S-35 in the area but less than
1/1000 for the non-occupational DAC.
