Linda , You are correct, The question was focused on the total site Record dose versus the total site estimated dose for a wear period. What is considered unacceptable?

As part of my review of the ED-TLD comparisons for each wear period I also look at the aggregate total period dose and ensure that it is reasonable compared to previous periods. I also plot all data and that information is also very useful for total system health purposes. Linda Linda M.

Does your site have an acceptance criteria for total period dose for the site? What difference between total site TLD and Estimated dose is considered unacceptable? If so, what is the basis for your criteria?
