study discussed above. Special studies using the FIDLER at other heights would be desirable. An important source of information is Tinney (1968), who discusses the calibration of the FIDLER instrument at 1-foot height. Also, a great deal of experience is presently being gathered on mobile field detectors in connection with the Enewetak Atoll cleanup effort (Ms. Madaline Barnes, Desert Research Institute, Las Vegas, should be contacted for statistical details). These data should be carefully studied. SYNTHESIS — Our principal contribution to the synthesis of soil, vegetation, small mammal, and cattle Pu concentration data appeared in Gilbert et atl. (1977a). Data for these sample types collected at the Project 57 site in Area 13 were plotted on a single graph as an aid to understanding the total data picture. Hypothetical Pu concentrations in tissues of a standard man assumed to live in and obtain most of his food from the area was also computed and plotted. These hypothetical values were obtained using the Pu transport and dose estimation model of Martin and Bloom (1976). Our synthesis efforts during 1977 involved relating estimates of Pu inventory in blow-sand mounds to previous Pu inventory estimates in surface soil (Gilbert and Essington, 1977). There is clearly a need for more extensive synthesis efforts in the future. Considerably more small mammal data is available now at several safety- shot sites than was the case in 1976. More cattle data from Area 13 are also available. How this synthesis effort should be organized is open to question. One approach would be to have one or two individual investigators be responsible for synthesizing certain available data and to assist in making recommendations regarding the design and coordination of future synthesis efforts. OTHER ACTIVITIES In Table 2, we list a number of statistical topics not discussed above that we have studied for the NAEG during the period 1971-1977. All references except numbers 16 and 18 were funded wholly or in part by the NAEG. This list does not include papers on these topics by other NAEG scientists that have appeared in NAEG publications or under NAEG sponsorship. 473
