Re: Dose Rates from Patients -Reply -Reply

I agree with Keith Brown - the regulation says:

  "... an area, accessible to individuals, in which radiation levels 
could result in an individual receiving a dose equivalent in excess on 
0.1 rem in 1 hour at 30 cm ..."

The operative word is could.  The physician could be exposed.  Therefore 
it is a high radiation area.

All opinions are well reasoned and insightful.
