NordRisk: Practical risk assessment for long-range atmospheric transport of radionuclides

摘要

Within the present NKS NordRisk project means for practical assessment of risks due to long-range atmospheric transport of radionuclides are being developed. Two complementary assessment tools are suggested: 1) An atlas over various dispersion and deposition scenarios based on historical NWP model data coupled to a dispersion model and 2) a simple diffusion model for the ensemble-mean radionuclide activity concentration, combined with a statistical description of the variability around the mean dispersion and deposition values.
