In this study, the PRESTO-II (Prediction of Radiation Effects
from Shallow Trench Operations) computer code f1) has been
applied for the following sites; Koteyli, Balikesir and Kozakli,
Nevsehir in Turkey. This site selection was based partially on
the need to consider a variety of hydroloqic and climatic
situations, and partially on the availability of data (2“4). The
results obtained for the operational low-level waste disposal
site at Barnwell, South Carolina, are presented for comparison.
The PRESTO-II model is an implementation of the PRESTO
methodology that was developed in 1983 for the U.S. Environmental
Protection Agency (EPA). PRESTO-II version of the code may be
characterized as to its intended applicability, the methods of
solution, code limitations, the existence of supporting software,
and required libraries. The purpose of the model is to estimate
possible health effects from low-level radioactive waste buried
in shallow trenches. The accumulation and distribution of
radionuclides in and through the environment is a complex process
involving both radionuclide decay and many interaction forms of
physical transport. It can take from hundreds to thousands of
years for a radionuclide to reach its maximum concentration at a
particular point in the environment. Radionuclide transport must
be represented by a model which emphasizes the dominant features
in radionuclide distribution over an extended time period.
PRESTO-II is intended to serve as a non-site-specific screening
model for assessing radionuclide transport, ensuing exposure and
health impacts to a static local population for a 1000-year
period following the end of the disposal operations.
