Table 1 shows the simulation results of PRESTO-II indicating that
the sum of all radiological impacts (both low- and high linear
energy transfer) from exposure of the local residence of Barnwell
(population of 7033) to contaminants is 5.53 10“4 deaths/y. The
linear energy transfer (LET) classification considers alpha
particles and the resultant recoiling nuclei to be high-LET
radiation. Beta particles and gamma rays are classified as low-
LET radiation. By comparison, the current annual death rate from
cancer for a representative population of 7033 would be 13
persons . The waste disposal-associated death rate is less
than the background cancer death rate by a factor of 4.2 10~5.
CONCLUSIONS
A methodology has been developed at the Oak Ridge National
Laboratory to assist in assessing the potential human health
impacts from disposal of low-level radioactive waste. This
methodology is called PRESTO-II. In this study, the PRESTO-II
computer code was chosen to evaluate radionuclide transport and
human health effects, and has been applied for various low-level
waste disposal sites in Turkey. Results of these simulation
suggest that there would be small health impact associated with
burying these wastes in low-level disposal area in either of the
Turkish sites described in this study. The predicted level of
health effects for the Kozakli site is comparable to that for the
Barnwell site but the predicted level of health effects for the
Koteyli site is greater then Barnwell site. Predicted population
radiation exposures for each of the three sites are well below
background levels. _f..,
