Abstract

The invention belongs to the field of radiation evaluation technology, and relates to a method for calculating concentration of radionuclide from a surface water discharging approach to aquatic organisms. The method comprises the following steps of (1), establishing a radionuclide transferring water power and diffusion model; (2), establishing a model of the radionuclide from water and suspensionsto fishes, and establishing a transferring model of the radionuclide from the suspensions and deposits to benthonic animals; (3), acquiring calculating parameters required in the models established in the step (1) and (2); and (4), calculating the accumulation concentration of the radionuclide in the organism. Through the method for calculating the concentration of the radionuclide from the surface water discharging approach to the aquatic organisms, more radionuclide transferring approaches can be considered based on a non-balanced state of the organism in absorbing the radionuclide, and more factors which affect the transferring factor are considered, thereby making a calculating result more accord with reality.

Description

technical field [0001] The invention belongs to the technical field of radiation evaluation, and relates to a calculation method for the concentration of radionuclides from surface water release pathways to aquatic organisms. Background technique [0002] Since the Fukushima nuclear accident, the radiation consequences of the liquid release of radionuclides have attracted people's attention, and the concentration of radionuclides from water to aquatic organisms is the focus of people's attention. [0003] The release of radionuclides from the liquid route in accident scenarios is sudden and non-uniform. In this case, radionuclides form pollution clusters in the water and transfer their activity concentrations with the flow conditions. Therefore, the time and space of radionuclides in water The distribution is non-uniform, and there is a concentration-clearing phenomenon in the absorption of radionuclides by aquatic organisms under this condition. [0004] The general method...
