Dose Investigation Procedure

[bflood@SLAC.Stanford.EDU (Bob Flood)]

I am planning an overhaul of our dose investigation process, and I am
looking for good ideas to steal. If you think you have a good process and
are willing to share your procedure(s) with me, please mail me a copy (or
e-mail would be even better). As we all should, please address any e-mail
directly to me at bflood@slac.stanford.edu rather than to the entire Radsafe
universe. Send regular mail to Bob Flood, SLAC, PO Box 4349, MS 84,
Stanford, CA 94309.

In addition to the investigation process itself, I am interested in the
following issues and the basis you have for your local practices:

1. How long do you wait for an unreturned dosimeter before you consider it
lost and initiate a documented investigation?

2. How many notices do you send a person about the unreturned dosimeter
before you give up?

3. How long (in your procedure) do you allow yourself to complete the dose
investigation? Does this investigation clock start running at the end of the
monitoring period or on the date the investigation was initiated?

4. Do you require an interview with the worker (if possible)? Do you require
that the final dose estimate be communicated formally to the worker as part
of the completion (i.e., do you send or give the worker an unsolicited copy
of the investigation or a dose report of some kind)?

I know that most of you nuclear power folks are confused about the concept
of unreturned dosimeters, but it really does happen and is a significant
problem for some of us.

Thanks in advance.
