Therefore, we will attempt to count 13 subjects in each of the 14 aforementioned categories, for a total WBC load of 182 subjects. We are requesting assistance from PASO in the following areas: 1. Notification of Utirik, Rongelap and Ujelang residents regarding our visit, and requests for necessary approvals from the Marshall Islands government and from the local leaders. 2. Advance preparation of Ujelang residents regarding the purposes of our visit and the nature of our personnel monitoring activities...To the best of our knowledge, none of the Ujelang residents have participated in our personnel monitoring program. Each subject will be asked to submit to the WBC procedure (~20 minutes including interview); and adolescents and adults will be asked to provide us with a 24 hour urine sample. We have reason to believe from the Majuro WBC experience that many people confuse the counting procedure with having an x-ray taken. This misconception should be avoided, and it should be understood that the subjects receive no radiation exposure from the whole body count. There was some mention at the Liktanir users group meeting that Ted Mitchell of MLSC is expected to visit Ujelang prior to our visit. Mr. I understand that. Mitchell supports our program activities in principle, and we would be happy to brief him on our objectives and procedures if he so desires. This is perhaps the path of least resistance in achieving advance notification of the Ujelang tod mt Mtchell agrees to help us, cor ” a assuming Mr. wi right. om people, and the timing of his visit is
