Abstract:
Objective To investigate the influence rule of the atmospheric Rainfall to the γ radiation Kerma rate in surface air in order to revise the resuh of its measurement during rainfall.Methods The influence factors of rainfall to the measurement of the γ radiation Kerma rate in air were analyzed and then the differential equation of the correlation factors was established theoretically,and by resolving the equation,the mathematical model Was obtained.The model was discussed through several practical examples.Results The mathematical model was coincided with the tendency of curve about the measured data on the influence rule of rainfall to the γ radiation Kerma rate in surface air.Conclusion By using the theoretical formula in this article which is established to explain the relationship between the rainfall and the γ radiation Kerma rate in surface air,the influence of rainfall to the γ radiation Kerma rate in surface air could be correctly revised.
