SONGS is in the process of replacing our portal monitors and are interested in what others are using and some additional related questions. Thanks in advance. 1. What make and model are you currently using? Canberra GEM-5 with 2" of lead. 2. Do you use a walk through or stand and count exit routine? Stand and count, typical time is 4 seconds at RCA boundary. 3. What is the sensitivity to CS-137 and Co-60 that you are achieving and how does that compare to the manufacturers advertised sensitivity? 75 nCi Cs-137 at 6". 4. Is the manufacturer easy to work with (technical support) and are parts easily accessible from them? We have a service contract and service reps who provide us great service. Otherwise, Canberra is a big company and has many layers to go through to get what you need. 5. Does the calibration process make sense (calibration menu), is it efficient (easily accessible data display), and does it require any peripherals (printers etc...)? It is a very good process and only requires an external keyboard hooked to USB port to navigate the menu. 6. Are they reliable? Yes, we've had them for about 5 years now. 7. Are they easy to work on? Yes, everything is very accessible.
