Has the work of NAEG at the safety shot sites come to a logical conclusion

The five years of study by the Nevada Applied Ecology Group of Pu and other radionuclides at the old safety-shot sites in Nevada have provided much environmental information, especially as relates to the nature, distribution, persistence, and amount of the contaminants present. There is, however, much important information on resuspension and on biological, edaphic, and hydrologic reaction mechanisms which yet needs to be obtained in order to help resolve the many questions concerning dissemination of transuranic elements into the natural environment. Several cases in point are discussed as examples. At least another five years of coordinative studies at the old safety-shot sites are highly recommended
