Palo Verde provides the following response: PVNGS does not currently have gamma sensitive monitors at the PA entrance; however, doing so is part of our near term planning. The benefit of detecting incoming personnel who have recently (and sometimes unknowingly) undergone a nuclear medicine procedure or have licensed material from another station is clearly a way to add rigor to your program. We had had sufficient site OE to justify making such a change. This is especially important when individuals have licensed material on them. Once they enter your PA and / or RCA and are detected during the exit process you make it more difficult to differentiate the original source of the activity.

There is very specific guidance for having the monitors at the exit to the protected area, but I cannot find anything for the entrance - I've spoken with both ANI & INPO on the topic. At FCS, we currently have them at both the entrance and exit to the protected area. Our reasons lie with both local and industry OE as well as a strong desire that we know about anything radioactive coming in the PA - from whatever source. Question: Does your site have gamma portal monitors at the protected area entrance & what is your reasoning?
