Looks like I am answering a bit late, but Ginna does use entrance portal monitors.
A big part of their usefulness is the ability to detect radioactivity that workers may have brought with them, undetected, from other plants before entering our controlled areas. This happens frequently enough that I believe the monitors to be a real benefit for us.

Considering the regulatory & oversight organization's stance on the issue as well as a very clear industry trend, my decision is easy - we are going to remove the PA entrance gamma portal monitors.

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?
