Make sure you evaluate your beta to gamma ratio. IE 81-07 states you need to meet 5000 dpm combined beta/gamma. With a gamma sensitive SAM, you need to consider your isotopic mix, and adjust the gamma set point accordingly.
From: [email protected] [mailto:[email protected]] On Behalf Of Pell, Bryan Sent: Thursday, January 27, 2011 11:38 AM To: '[email protected]' Subject: Powernet: Sensitivity Study Benchmark At Ginna Station we have performed a sensitivity study on our personnel exit monitors, basically seeing how low we can reasonably go with our alarm set points and adjusted them accordingly. The question has come up about the SAMs. Does your site set the alarm set points to 5,000 dpm or have you performed tests to see how low you can go and adjusted accordingly? Thanks for your input...
