Ken, We implemented bulletin at the beginning of 2018. All of our portable instruments (friskers, ion chambers, area monitors, etc), PCM's, TEM's and GEM5's went to weekly.
We started tracking for performance issues once we went to the weekly source checks and have not seen noticeable difference in equipment performance at this time. Hope this helps, John Ainsley Radiation Protection Supervisor - RP Instruments Fermi-2 Nuclear Power Plant 734-586-5862 Office [email protected] <mailto:[email protected]> [http://quest.dteco.com/news/images/newBrandingStory.jpg] PROPRIETARY, CONFIDENTIAL OR PRIVILEGED COMMUNICATION *** This communication may contain proprietary, privileged or confidential information protected by law.
