Resuits and Discussion of Body Burden Estimation Figure 69 shows some representative wholebody gamma-ray spectrographsobtainedin the 1965 survey. The AEC team is seen to have a spectrum not markedly different from the backgroundspectrum exceptfor the natural *°K peak and a trace of '*’Cs, whereas the Rongelapese have significantly 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 surveys had disappeared by 1965. Table 26 summarizes the whole-body counting results, and the individualvalues are presented in Appendix 17. Theresults of the urine radiochemi- cal analyses are displayed in Table 27. Inspection
