Model for Reconstruction of γ-Background during Liquid Atmospheric Precipitation

With regard to reconstructing the gamma background dose rate, existing models are either empirical with limited applicability or have many unknown input parameters, which complicates their application in practice. Due this, there is a need search for new approach and build convenient, easily applicable universal model. The paper proposes mathematical model temporal evolution of ambient equivalent γ-radiation rate during rain episodes, depending on density radon flux from soil surface, as well duration intensity rain. efficiency confirmed by high coefficient determination (R2 = 0.81–0.99) between measured reconstructed periods rain, simulation was performed using Wolfram Mathematica. An algorithm developed restoring dynamics rainfall. Based results obtained, assumptions were made where washout radionuclides originates. influence ratio increase total investigated.
