Abstract:
Radon and its short-lived decay daughters are the main source of radiation on natural ways for population. The Radon gas, exhaled from soil, water or construction material is producing by radioactive decay the following solid daughters: Po-218, Bi-214, Pb-214, and Po-214, which can attach to aerosols, and consequently penetrate the organism by inhalation. The human respiratory tract can be approximated by aid of a compartment model that takes into account the different anatomical structures exposed to contamination and irradiation, as well as the respective physiological processes. This model is associated to a mathematical equations system that describes the behavior of the radioactive material inside the body. The results represent the dose equivalent on different organs and tissues, as function of subject and the activity performed in contaminating environment.
