Abstract: The dose distribution in the lung is inhomogeneous. The dose to the basal cell layer of trachea and main bronchi is much higher than the dose to total lung both for rabbits at different ages and for different animals. A maximum value of the dose to lung tissue for rabbits at ages of 20-40d is observed. The dose decreases with increasing body weight. The relationship between the dose and body weight can be described by a power function. The dose to total lung increases exponentially with the mimute breathing volume per unit of lung weight.
