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
