ORNL-6785 Oak Ridge Mortality Study
For Details See Dose-Response Analyses.
A smaller group of 28,347 white males employed at X-10 or
Y-12 who were at risk for exposure to external penetrating radiation was
examined to determine if there was a relationship between rates of death
from selected causes and level of radiation dose.

- A 20% decrease of deaths overall, compared with national death
rates. (see Table VIII)
- A 13% decrease of deaths from cancer compared with national
death rates. (see Table VIII)
- A significant association between external
radiation dose and death from cancer (all cancers taken
SEE Table VI and
Fig. 2A and Discussion
- Among the specific cancer categories analyzed:
- Additional analyses were performed using radiation doses that
were adjusted to account for dose estimates that may have been
too low for workers during the early years of operation of the
facilities.See Effect of ''Missing Dose"
on Analyses and
Mitchell et al.).
These analyses showed a decreased magnitude of the
dose-response coefficient.( see Tab. IX ,Tab. X )
