Review DRI estimate plots, conversion factors (ratios, van calibration, ete.) and error terms and comment to ERSP Manager on believability. G. H. IV. Assist the Tech Advisor, when requested, in selecting the in situ locations to be soil sampled. Obtain additional data as requested by DRI or DOE. DRI Provide statistician for data evaluation who will: l. Receive in situ data from EG&G, 2. Receive soil data from EIC (ground truth-Am, Pu, Pu/Am ratios). 3. 4, Determine Van to Am, Am to Puor Van to Pu ratios and errors to be used at each in situ location. Receive EG&G, EIC and DOE comments on the believability of these factors. Return personal rebuttal comments to ERSP Manager or take action to correct situation commented on if required. Request and/or comment on usefulness of taking additional data by EG&G or EIC. 6. Construct estimate plots including errors. 7. Comment on estimate maps and their usefulness. EIC a hoo foP V. 5. Provide manager for overall laboratory and equipment maintenance direction. Provide Soil Sampling Supervisor to direct the actual collection of soil samples. Arrange for sereening,* on island storage or transport of soil samples to laboratory. Receive soil samples from boat at Enewetak Island and transport to laboratory. Sereen and prep samples, then gamma sean for Am and fission products. Determine by appropriate methods 238 py and 239,240 py content of samples. Determine by gamma spectroscopy 241 Am content of samples as well as analyze a statistically valid number of samples for 241 am by chemical methods. Establish and perform quality analyses in laboratory. Transmit data to DRL Comment on conditions of each soil sample. Review DRI estimate plots, conversion factors (ratios, van calibration, ete.), and error terms and comment on believability. Obtain additional data as requested by DRI, EG&G or DOE, *As used herein, the word screen means to perform preliminary evaluation of the level of radioactive contamination. Screening in the sense of passing material through a sieve was not done. A-1-2
