MR. LEWIS [Robert Lewis, Director of NRC’s Division of Preparedness and Response]: Okay. Good morning. I will cover four things that occupied most of the protective measures team time last night. First, there was a flight by NARAC last night […] We also are working — there was a request coming from last night — before last evening’s shift to develop projections for doses in California. And that is — has been in process. We will need to — in order to do that, we will need to engage with — we already have engaged with the Office of Research. We are looking to engage further with Sandia to make some modifications to the (inaudible) to effectuate those dose estimates in California. In conjunction with that, there was a DITTRA and NARAC dose estimate that was done for California that we obtained as part of the DOE briefing package. And those were estimating what we believe to be very high doses to children, and a thyroid (inaudible) dosage. We think that (inaudible) extremely conservative modeling related to those doses and assumptions. It’s a thyroid dose that involves deposition of material and (inaudible) integrated the dose over a year or two, for example, drinking milk from the same cow that’s grazing on the same contaminated field the entire time, things like that. But once we get the (inaudible), we will have something to compare (inaudible). Also, when we saw those dose estimates, we looked in the historical record for any kind of information related to Chernobyl actual deposits that were measured. We did find some and (inaudible) dose activity per area of deposits that were estimated — I think they were provided from DITTRA. We did the same dose calculations with those concentrations, and the doses were approximately 1,000 times lower. So we were in the one to 10 millirem range versus full rem range, which was — full rem thyroid dose range, which was being (inaudible) by DOE and DOE (inaudible). […]
