Pr. James L. Liverman Page Two It was interesting that while at Bikini the subject of Pu was not brought up by the people. We told them that low levels of the isotope were found in their urines and that we were keeping constant tab on this and other radionuclides by urine analyses and whole body counts. Dr. Cohn presented a talk on radiation on Bikini compared with Rongelap and Utirik and some higher level areas of the world. The people asked us many questions; there was much discussion and the meeting lastes several hours. I welcome the meeting at ERDA on May 16th since many of us here feel the need for clarification of responsibilities with so many groups involved in the bioassay program in the Marshalls.
