Occupational Radiation Exposure at NRC Licensed Facilities
The amount of material taken into the body
is given in microcuries, a unit of measure of
the quantity of radioactive material. For each
licensee category, the maximum number of
intake records and the maximum intake are
highlighted in the table in bold and boxed for
ease of reference.
Table 3.8 lists the number of individuals with
measurable CEDE, the collective CEDE, and
the average measurable CEDE per individual
for each licensee category. Fuel fabrication
facilities and the UF6 production facility had
the majority of internal dose (99%) in 2010 and
the highest average CEDE per individual. This
is due to the individuals' exposures to uranium
during the processing and fabrication of the
Table 3.9 shows the distribution of internal
dose (CEDE) from 1994 to 2010 for licensees
required to report under 10 CFR 20.2206. For
the purposes of this table, the definition of a
"measurable CEDE" is any reported value
greater than zero. As noted above, the vast
majority of the internal doses are received by
individuals working at fuel fabrication facilities.
The collective CEDE has decreased nearly
every year since 2000 but increased in 2010.
While the collective CEDE increased by 5%
in 2010, the average measurable CEDE
decreased by 6% indicating that while more
individuals performed work receiving dose, the
average dose received by the workers did not
