Radon dose conversion factor

Dear radsafers,

 There was a conversion factor of 1mSv/y  per 20 Bq/m3 radon concentration

quoted from NRPB(Exposure to Radon daughters in dwellings, 1987).Are there

any dose conversion factors calculation for radon other than this figure? I

am in search of the radon and radon progenies dose calculation in different

parts of the lung.

  I also came to a difficulty when applying table 12- aerodynamic particle

deposition of ICRP 66 (pg 43) that region BB of the lung has assymmetry of

deposition parameter in [inhalation] path and [exhalation] path which seems

to be not reasonable for me!

  Thank you for any help in this topic.
