[ RadSafe ]Smoking - radon risk

[John R Johnson]

Franz et al

The dose distribution in the lungs changes with the size distribution of
aerosols and this different in smokers' and non-smokers' houses, but I don't
think we know enough about the relationship between dose distribution and
lung cancer to be able to conclude anything.

You can find more information in "Dosimetry Aspects of Exposures to Radon
and Thoron Daughter Products" OECD 1983.

I remember that many years ago the effect of smoking on lung cancer caused
by indoor radon progeny was discussed as originating from changes in the
ratio of attached and unattached fractions. As far as I remember it was
concluded that smoking would reduce the radon risk - but of course not the
smoke cancer risk...... Sorry, I do not remember the reasoning.
