EPIDEMIOLOGY RESOURCES, INC. September 9, 1981 Mr. Stephen H. Green leigh Acting Deputy Assistant Secretary for Environment, Safety and Health Department of Energy Washington, DC 20585 Dear Mr. Greenleigh: We are pleased tc submit a proposal in response to your letter of August 19, 1981, to Mr. Jonathan Weisgall. Although implicit in our technical proposal, I would like to emphasize that the four points you raised in that letter will be met. We believe that examining only forty (40) environmental samples is cutting it close and we would prefer more; however, we agree to this in order to expedite the contract. In accordance with accepted international practice, the dosimetry will be based on two kinds of assay: (1) analysis for gamma-emitting nuclides by gamma spectrometry, and (2) specific chemical analysis for plutonium and strontium-90. Under ordinary circumstances, roughly sixty (60) days are required for these ana,lyses. Since the development of the report depends heavily on the results of these analyses, we cannot guarantee completion of this project within 90 days, although we will make every effort to do so. Further, since you have requested that Lawrence Livermore National Laboratory conduct duplicate analyses, it will be important for the results of those analyses to be cited in this report for comparative purposes. Therefore, the final report could be held up if Lawrence Livermore National Laboratory cannot keep to the tight time schedule required by this project. This proposal is a firm offer for sixty (60) days from the date of this letter. Upon notification by the Department of Energy, we guarantee to begin-work within three (3) weeks. We will make an effort to coordinate our travel plans with DOE laboratory personnel, unless such coordination is clearly impractical. Respectfully submitted, lwq~~ Nancy A. Dreyer, MPH, Ph.D. President mot P. O. Box57, Chestnut Hill, Massachusetts 02167(617) 734-?100
