Columbia's response.
1. Have you ever seen higher TLD results for a majority of workers on any particular job(s)? If so, which one(s)? Not that I can recall, this would only happen for a very specialized task that would require TLDs to be read at the completion of the task. 2. Have you ever required that the TLD and ED be kept together (for example in a bag) for a particular job to eliminate placement differences? Yes, when the ED is relocated or dose gradients are expected.

Hello All, At Millstone, we recently discovered a trend where a majority of individuals working on our ECCS sump strainer cover installation had TLD doses higher than the ED estimates (ICES #305595). A couple follow-up questions: 1. Have you ever seen higher TLD results for a majority of workers on any particular job(s)? If so, which one(s)? 2. Have you ever required that the TLD and ED be kept together (for example in a bag) for a particular job to eliminate placement differences? Thanks!
