Re[4]: MONITORING UNIVERSITY HEALTH CENTER PERSONNEL

     Kent, let me clarify the note about the 100 mrem limit. I was not 
     referring to patients receiving either diagnostic or therapeutic 
     evaluations. I was only referring to and individual who has access 
     around the facility. I hope that clears that up.
     
     As far as nuclear power plants, we are "forced" to provide some form 
     of monitoring to all individuals who gain access to our radiation 
     controlled areas who will NOT exceed the 100 mrem threshold, NOT by 
     the NRC, but by ANI. If we project that the individual will exceed the 
     100 mrem per year, then 2 types of dosimetry must be provided. So, 
     while the NRC says that monitoring is not required for individuals 
     <500 mrem/year, we provide monitoring to all individuals. We establish 
     that we meet the 100 mrem limit for individuals who do not access the 
     radiation controlled areas but access our property and may be exposed 
     to areas that have the potential for exposure from our licensed ac
     tivities using control badges throughout the plant as well as on the R
     CA fence. Hope this also clarifies my comments.

If indivi
     du
     als are not to be monitored at all, then a very good program mus
     t be in place to ensure that exposures can't be received, during vari
     ous work evolutions. If that can be done, then you probably have a case
     . But then again, we deal with jurors who don't necessarily see the ris
     k from radiation being as low as we do.

Regards,

No, this is not true.  The NRC has stated that this does not apply to 
patients released (and one can argue releasable) in accordance with 10 CFR 
35.75.  

But what I don't understand is why this logic does not apply to 
unmonitored workers.  That is what the original question asked.
