Re: Patient release criteria (Reg Guide 8.39)

["Sandy Perle" <sandyfl@ix.netcom.com>]

I'll ask some questions, showing my ignorance related to release of 
patients undergoing diagnostic or therapeutic uptake studies or 
implants. Is the Reg. Guide considered regulatory in nature? In 
other words, have you incorporated the Reg. Guide into your License 
and procedures? The last question has to do with the dose rate. Does 
the Reg. Guide state a dose rate PER hour, or, does it state a dose 
IN an hour, i.e., 5 mrem/hr is not the same as 5 mrem in an hour. Can 
occupancy factors be incorporated to determine that the probablility 
of an individual being exposed to an individual with the implant will 
not realistically exceed the dose threshold. I would be interested in 
what the specific requirements are, and, what assumptions a facility 
MAY consider when releasing or not.

Thanks for any information.
