The range in the amount of a radionuclide in the same tissue from the same species at the same islet is wide. When detectable amounts of radionuclides are present, the minimum and maximum values often differ by factors of four or five and sometimes by a factor of ten. The values for concentra- tion of radionuclides in individual samples are given in Appendix Tables 1 through 15, Average values and ranges are ent of Eneray artm . given in text Tables 1 through 15. Petaistorian’s Otfice -# ARCHIVES” Dry weights were used for the basic calculations because the true water content of some samples is difficult to determine. The average concentrations of radionuclides were converted to a wet-weight basis for convenience in calculating daily intake from the diet; the conversions were made by using average wet to dry weight ratios for each kind of sample.
