Establishment of detailed respiratory tract model and Monte Carlo simulation of radon progeny caused dose
As radon is one of the most important natural radiation sources, its radiation hazard has always
been a concern. α and β particles emitted by short-lived radioactive radon progeny nuclides could
result in a high local dose and induce radiation damage to the respiratory tract. A detailed
respiratory tract model needs to be built and dose distribution in the respiratory tract should be
studied to reflect the characteristics of energy deposition caused by radon and its progeny.
Therefore, in the present work, a dosimetric study was conducted on the respiratory tract and
non-uniform dose distribution in the bronchial region was studied. First, a detailed voxel
respiratory tract model was established based on the anatomic bronchial parameters of an adult
Chinese male. The dimensional parameters of the tracheo-bronchial tree of an adult male adopted in
