Air sampling practices

[avest@magnus.acs.ohio-state.edu (Albert Lee Vest)]

Colleagues,

I've only gotten one response so far, so I'm re-posting this request.
"Utilities Welcome", but information from research labs / universities would
be more useful.

The Committee has asked me to gather information on how other institutions
"decide need for breathing-zone monitoring and how they do the actual sampling."

Please respond directly (avest@magnus.acs.ohio-state.edu), if you wish to
participate, to the following:

What condition(s) have been established at your institution to trigger:
 - one-time workspace air sampling for radionuclides?
 - periodic workspace air sampling for radionuclides?
 - continuous workspace air sampling for radionuclides?
 - one-time breathing zone air sampling for radionuclides?
 - periodic breathing zone air sampling for radionuclides?
   - Use of breathing zone air sampling data rather than
     bioassay data for assignment of internal dose?
   - Routine use of respiratory protection for internal dose reduction?
 - Posting rooms as "Airborne Radioactivity Areas"?
 - Removing "Airborne Radioactivity Area" postings from rooms?

Have any of the above practices ever been done at your institution?
 - Please answer Yes or No to each on list above.
 - If Yes, please briefly describe how it was done - sampling device used,
   filter material used, radioassay technique + instrument used.
 - Would you do it the same way (or at all) today?

Are triggering conditions and/or sampling techniques described in official
procedures?  How often are these procedures reviewed or updated?  Whose
approval is necessary, at your institution, to make new or updated
procedures official?

Confidentiality provided on request.
Thanks in advance for all willing sufferers.

Note 1 - I'm not asking about stack effluent sampling.
NOte 2 - Please don't clutter radsafe with your replies.  See above.
