Since their (the NRC's) own guidance on ede use includes a section on the use of a lead apron, I would be forced to conclude that that is an individuals opinion, not based on any hard science.
At Entergy we have used the vests at at least 4 sites successfully. We have no issues. Our implementation addresses the shallow dose and lens of the eye dose specifically, so I believe that we have it covered. We have had NRC inspections at each site since the use of the vests. I can give you contacts if you need to discuss this with anyone.

During the post outage NRC inspection, the regional HP inspectors voiced serious concerns about their usage and spent time assuring themselves that we did not use them. So more work to do before we use them. ________________________________ From: "Courtenay, Christopher C" [[email protected]] Sent: 02/09/2011 09:26 AM EST To: "[email protected]" <[email protected]> Subject: Powernet: Tungsten Vest Duke Energy would like to know the following: For anyone who uses a tungsten/lead vest or apron, have you noticed any abnormal or different than expected response of the TLD and ED underneath the vest/apron other than the expected reduction in dose? Specific items of interest are ED response changes, TLD response changes, changes in observed shallow doses. Thanks!
