Re: Microfuge contamination

["Dave Lane" <dave@cehs.siu.edu>]

We allow 2000 dpm inside a centrifuge here at Southern Illinois University.
 For comparison, we allow 200 dpm for loose surface contamination outside
such restricted areas.  Another limit we have is 1000 dpm inside a
designated radioactive fume hood.  If I can be of further service please
feel free to ask.
