At DCPP, our procedure allows use of an alternate method for radon. Here's the step from our procedure:
Alternate Method (For Essential Personnel Only) 1. An individual may be released if he/she meets all of the following conditions: * An RP technician has performed a direct whole body frisk of the individual and detected < 100 ncpm β-γ. * There is positive indication of contamination from radon only. * The individual was not engaged in CA work activities. * The individual enters a Portal Monitor and the monitor does not alarm. Essential personnel are identified as: (e.g., security or operations watch standers, RP technicians) From: [email protected] [mailto:[email protected]] On Behalf Of Benjy P Bertossi Sent: Wednesday, February 26, 2014 11:11 AM To: [email protected] Subject: Powernet: RCA exit followup Is anyone releasing personnel from RCA, without being able to clear PCM with no alarm, if they have determined that PCM alarm is due to radon as determined by using gross alpha / beta hand frisking (e.g. CM11) and visually determining from count rate, that apparent decay time is short?
