DOSE CALCULATIONS<br />

Dilution will likely reduce concentration <strong>of</strong> radionuclides in the water by adsorption<br />

or other mechanisms while the total water usage will remain the same. Therefore, total<br />

radionuclide intake is. expected to be less as in population and individual dose. If it were<br />

simply a matter <strong>of</strong> dilution in water, the comment would indeed be correct.<br />

Draft pp. 3.1.165-168<br />

Issue<br />

Doses to individuals are said to be due in the first year predominantly to direct radi-<br />

ation. Food pathway doses to bone "increase substantially" during the 70-yr dose accumula-<br />

tion pathway. It is not clear why. We have been able to roughly check these values. (154)<br />

Response<br />

The increase in 70-yr dose commitment to bone is because <strong>of</strong> the buildup <strong>of</strong> actinides<br />

in the bone. No clearance <strong>of</strong> actinides from bone is assumed by the models used.<br />

Draft p. 3.1.179<br />

Issue<br />

Since the releases in Table 3.1.58 are suspect, so are the population dose values in<br />

Table 3.1.59. (154)<br />

Response<br />

No problem was found with draft Table 3.1.58 and the dose values in draft Table 3.1.59<br />

are believed to be correct.<br />

Draft p. 3.1.192<br />

Issue<br />

The overstated value for 14C in Table 3.1.68 would imply that Table 3.1.69 should be<br />

in error, particularly for world-wide dose which is totally dominated by 14 C, but the<br />

quoted figures cross check with Section 5.4.2.4 <strong>of</strong> DOE/ET-0029. Before issuing the final<br />

EIS it should be determined which figures are correct. (154)<br />

Response<br />

The value for 14C was given incorrectly and has been adjusted. However, the world-<br />

wide dose in draft Table 3.1.69 is correct as shown in the draft.
