Hello, What DAC value to do you use for alarm set points on AMS-4 (or similar Continuous Air Monitor)? South Texas Project has been using 1E08 μCi/cc as it is the DAC for unknown βγ/60Co; however, it can be too conservative when the predominant nuclide is something with a less restrictive DAC, such as 51Cr or 58Co. Does anyone use a composite or effective DAC for areas such as around the reactor cavity where contamination is not likely to be aged?
