RADON DENSITY PROFILES IN ALVEOLAR PORES: AN INTEGRAL EQUATION FORMALISM APPLICATION

In this work, we obtained density profiles of Radon particles near the alveolar wall surface by the development of a theoretical model that describes the interaction between such particles and the alveolar wall cells. The model captures relevant biological and physicochemical characteristics such as the width of the alveolar wall and the energy required for the Radon particles to pass through it. The system satisfies the conditions to be considered in thermodynamic equilibrium and under normal pressure and temperature conditions. We numerically solved the Ornstein-Zernike equations derived from the integral-equation formalism and showed the effects of changing the alveolus size, the alveolar wall width, and the energy required to pass through its Radon density profiles. Our method is a helpful tool in biophysics and other related areas.
