Paducah Site<br />

The 50-year CEDE (internal) from DOE air<br />

sources to th~ maximally exposed individual,<br />

who under most circumstances is the person<br />

living. closest to the plant in the predominant<br />

wind direction, is calculated ·each year. The<br />

maximally exposed individual for 1999,<br />

identified through modeling, is located<br />

approximatelyH>80 meters (3543 ft) northnortheast<br />

. of the. ,plant site. The dose to the<br />

maximally exposed individual from radioactive<br />

emissions was calculated to be L 7 X 10- 3<br />

(0;0017) mrem which is well below the lO-mrem<br />

limit of 40 CPR Part 61, Subpart H.<br />

Conclusions<br />

Table 6.3 provides a summary of the dose<br />

for 1999 from the Paducah Site that could be<br />

received by a member of the public assuming<br />

worst-case exposure from all major pathways.<br />

The' largest contributor to the calculated dose is<br />

from ingestion of deer meat. The groundwater'<br />

pathway from' DOE sources is assumed to<br />

contribute no dose to the population because all<br />

residents have been supplied with public water<br />

by DOR The worst-case combined (internal and<br />

external) dose to an individual member of the<br />

public was calculated at 0.69 mrem. This level<br />

is well below the DOE annual dose limit of<br />

100 mrem/year to members of the public and<br />

below the EPA limit of 10 mrem.<br />

Estimates of radiation doses presented in<br />

this report were -calculated using the dose factors<br />

provided by -DOE and EPA guidance documents.<br />

These dose factors are based on International<br />

Commission on Radiological Protection<br />

Publication 30, Limits of Intakes of Radionuclides<br />

by Workers ~ICRP 1979). Figure 6.3 shows the<br />

potential (worst-case) annual dose as calculated<br />

for the past five years.<br />
