False! The radon concentration is still constant. Smoking reduces unattached fraction of radon progeny in air. Consequently,  the lower concentration of

unattached fraction reduces the dose for the lung. See the values of dose conversion factors for different diameters of particles (ICRP 66),

Porstendorfer and Reineking's  (I recommend Zock, Porstendorfer, Reineking: The influence of biological and aerosol parameters of inhaled short-lived

radon decay products on human lung dose. Rad.Prot.Dosimetry, 63, 1996) or Jacobi and Eisfeld's works.
