[A model of regional deposition of aerions in the human lungs]. 1984

The numerical solution of the equation of airions mass transfer in the human lung is obtained considering diffusional deposition. More than 90% of airions inhaled during breathing are deposited. The deposition occurs in the first 10-12 generations of the lung tree, and therefore the airions do not reach the alveolar region.
