Annual Site Environmental Report for 1999
'Dose
Abstract
For 1999, exposure pathways potefJtlally contributing to dose were determined to include ingestion of surface
water, ingestion of sediments, ingestion of deer meat, direct radiation, and atmospheric releases. Th~
highest estimated dose a maximally exposed individual might have received from all combined DOE exposure,
pathways (worst-case scenario) was 0.69 mrem. This dose is a small fraction of the applicable federal dose'
standard of 100 mrem/year.
Introduction
This section presents the calculated doses
to individuals and the surrounding population
from atmospheric and liquid releases from the
Paducah Site, as well as direct radiation (Sections
4 and 5). In addition, potential doses from
special case exposure scenarios, such as deer
meat consumption, were calculated based upon
deer sample analyses.
DOE Order 5400.5, Radiation Protection
of the Public and the Environment, limits the
dose to members of the public to less than 100
mrem/year total effective I~ose equivalent from
all pathways resulting from operation of a DOE
facility. Information on the demography and
land use of the area surrounding the plant and
identification of on-site sources have indicated
certain radionuclides and exposure pathways.
