Abstract

The time-dependent radioecological model applicable to Korean environment has been developed in order to assess the radiological consequences following the short-term deposition of radionuclides in an accident of nuclear power plant. Ingestion food chain model can estimate time dependent radioactivity concentrations in foodstuffs. And the system dynamics approach is useful for analyzing the phenomenon of the complex system as well as the behavior of structure value with respect to time. System dynamic model is used to construct the transfer mechanism of time dependent radioactivity concentration. Dynamic variation of radioactivities were simulated by considering several effects such as deposition, weathering and washout, resuspension, root uptake, translocation, leaching, senescence, intake and excretion of soil by animals, intake and excretion of feedstuffs by animals, etc. The input data to the model are the time of the year when the deposition occurs, the kinds of radionuclides and foodstuffs for estimation of deposition. The output of this model (Bq ingested per Bq m-2 deposited) may be multiplied by the deposition and a dose conversion factor (Gy Bq-1) to yield an organ-specific dose estimate. The model may be run deterministically to yield single estimates or stochastically ("Monte-Carlo" mode) to provide distributional output that reflects uncertainty in the output due to uncertainty in parameters.
