Concentration factor method: A tool for the evaluation of radiation effect on the environment

摘要

The increased risk to other species may be resulted from higher doses due to elevated concentration of radionuclides in environmental media or biota and/or different sensitivity to ionizing radiation. The methodology of the dose estimation for human beings is adequate basically for other species, too. The activity concentration of radionuclides can be estimated by the concentration factor method commonly used for terrestrial and aquatic food-chain models. The radiosensitivity of different species is characterized by the lethal doses, however there is less data on the risk of stochastic effects on non-human species.
