Risk estimates for lung cancer related to radon in homes can be derived by at least two quite different approaches. Differences in doses and dose rates can be addressed in laboratory experiments in radiobiology. ShIl, the data available for this purpose are limited and risk estimates are subject to major uncertainties.
Cat are dense columns of ionizations, which give rise to the locally high radiation dose deposited.
Serous cells . Ranges of two a particles emitted by radon progeny deposited on lung surface and average depths of serous and basal cells in h Amen lung, according to study of several hundred nnormaln lung sections from Pathology Department at Columbia Presbyterian Medical Center. An obvious mechanism for hong out a suppressor gene is radiation-induced deletion. A tumor suppressor gene acts in a recessive way, so the deletion would have to occur in both chromosomes of a pair, an event of very low frequency. The cells in the tumor then have two chromosomes that originated from the same parent.
