Results and Discussion of Body Burden Estimation Figure 69 shows some representative wholebody gamma-ray spectrographsobtained in the 1965 survey. The AEC team is seen to have a spectrum not markedly different from the background spectrum exceptfor the natural ‘°K peak and a trace of '*’Cs, whereas the Rongelapese havesignificantly higher '**Cs peaks. Analysis of the curves indicates that the *°Co valuesare also detectable in many of the Rongelapese. As had been anticipated on the basis ofits relatively short physical half-time, the **°Zn seen in previous sur- veys had disappeared by 1965. . Table 26 summarizes the whole-body counting results, and the individual values are presented in Appendix 17. Theresults of the urine radiochemical analyses are displayed in Table 27. Inspection
