# Finite Difference Solution of Diffusion Equation Describing the Flow of Radon Through Soil with Uncertain Parameters

Conference paper
Part of the Lecture Notes in Mechanical Engineering book series (LNME)

## Abstract

In this paper, an imprecise radon diffusion transport through soil is investigated. As few such researchers have already studied Radon diffusion problems with crisp parameters. Due to various factors, there is a chance of impreciseness to occur in the involved parameters of the model while doing the experiment. So handling a differential equation with imprecise parameters is a challenging task. Accordingly, a second-order radon diffusion equation with imprecise parameters considered as intervals has been studied here. The solution of the considered diffusion equation is modeled by using modified Explicit Finite Difference Method (EFDM) along with parametric concept and for the validation, results are compared with the crisp solutions.
