We check each detector at the center 6 inches away from the detector. We then step into the monitor holding the source at the chest.

From: [email protected] [mailto:[email protected]] On Behalf Of Eaton, Eric Sent: Tuesday, July 02, 2013 1:27 PM To: '[email protected]' Subject: Powernet: Portal monitor Greetings all... After attending the Canberra User's Group Meeting last week, it came to light that some facilities perform the Daily Source Check on their Portal Monitors differently. Thus the basis for my question... Does your facility source check each detector of your portal monitor using the alarm test function(like the Argos or PM-7)? Or Do you source check your portal monitor by placing the source in the middle of the monitor using the alarm test function? Or Do you source check your portal monitor by having a technician step into the monitor (in normal) with the source on their person? Or, something else? Thanks in advance for your responses...
