FASSET Framework includes the following fundamental elements: source
characterisation; description of seven major European ecosystems; selection of a
number of reference organisms on the basis of prior ecosystem and exposure analysis;
environmental transfer analysis; dosimetric considerations; effects analysis; and, as an
integral part of the aforementioned steps, general guidance on interpretation, including
consideration of uncertainties and possibilities to extrapolate from existing data to areas
where data are absent or scarce. The project has used existing information,
supplemented by the development of models, by performing Monte Carlo calculations
to derive dose conversion factors, and by building an effects database (FRED, the
FASSET Radiation Effects Database). |
