The accuracy of our proposed model was verified by comparing it with the measured data of the fractured rock. The results demonstrate that fluid convection in fractures drives radon migration, which is dominant compared to the diffusion process.

The governing equations for radon migration in fractures and the rock matrix were established and numerically solved using the finite element method. The paper provided a detailed method for determining the locations of three-dimensional fractures using the multiplicative cascade process. This paper proposed a novel model based on a fractal discrete fracture network (DFN) to simulate radon migration in fractured rock masses. Numerical simulation of radon migration in fractured rock masses is crucial for environmental radon pollution protection, radon tracing technology and the co-exploitation of coal and uranium resources.
