[ RadSafe ] HEPA Filters

[Patrick Muldoon]

Thank you Peter for telling the world "we should know 
better" at NASA Ames. Truth is, we do. Most of the HEPA 
filters are legacy filters that were installed years ago - 
maybe, maybe not for radiological purposes. While I am not 
currently serving as RSO, when I was the Radiation Safety 
Committee was informed that there was no requirement for 
HEPA filters for the work they were doing. I'm sure 
Berkeley knows better as well and has their own reasons 
for having HEPA filters. I wish you luck tracking down the 
requirement. I'm guessing it comes from some worse case 
scenarios where powders or dusts may be generated.
