“…Therefore a salinity-driven submodel for the uptake in the lowest trophic level (phytoplankton) is of importance, since caesium enters the foodweb via phytoplankton. For strontium however, accumulation in the foodchain hardly occurs [7]; direct uptake via the gills of marine fish contributes to a higher extent to concentration in fish, than it does in the case of caesium. At the higher trophic levels, the reason is that radiostrontium accumulates in the bones (target tissue) of prey fish and is diluted by the not contaminated flesh of the prey in the stomach of the predator.…”

Abstract. This work is based on the describing a new approach in estimation of Concentration Factor (CF) for marine organisms radionuclides uptake. We considered the dependence of CF from the water salinity (determining the K + and Ca 2+ ions). The radionuclide uptake by the marine biota of Dnieper-Bug Estuary using the numerical compartment-model POSEIDON-R with latest modifications was applied. The levels of radionuclides in the different marine organisms, representing the various types of marine organisms in the different trophic levels of the foodweb, were calculated. The uptake model takes into account both the uptake of radionuclides via food consumption, by describing the predator-prey relations, and the direct uptake of radionuclides from the water via the gills.

“…Human-health risks are then calculated based on data and models that relate exposures to risk (Till and Meyer, 1983). Two measures are commonly used to describe the probability that harm will result from exposure to a risk agent (Cohrssen and Covello, 1989): 1) Individual lifetime risk --the estimated increase in probability that an individual will experience a specific adverse health effect as a result of exposure to a risk agent over a lifetime; and 2) Population risk --the estimated number deaths in the exposed population.…”

“…Input data for dose calculations will be taken from several readily available sources (transfer factors from Baes et al, 1984 andMeyer, 1983; ingestion rates from NCRP, 1984 andMeyer, 1983; Committed Effective Dose Equivalents (CEDE) from U.S. DOE, 1988b, which has replaced U.S. DOE, 1985). The CEDE factors will be taken from U.S. DOE, 1988b, because that document is intended to be used as the primary reference by the DOE and its contractors for calculating dose equivalents for the public resulting from the ingestion or inhalation of radionuclides.…”

“…For example, ingestion rates for beef consumption range from 86 g/d (NCRP, 1984) to 206 g/d (Till and Meyer, 1983). The beef consumption rate of 86 g/d assumes that other meats are eaten as well.…”
