Selected quotes from the paper:


“The estimation of the risk of LC due to RRn exposure was performed
according to the cancer risk model developed by the BEIR VI.(4)”


“It is important to keep in mind that the BEIR VI model used in this study
to assess LC risks posed by indoor radon and cigarette smoking are subject
to considerable uncertainty because of gaps in scientific knowledge of radon
effects at low levels of exposure. Of the two risk models developed by the
BEIR VI committee, the concentration-form of the model was preferred in the
present assessment in order to be more conservative. Even if the
duration-form model corresponds to the well-established inverse dose-rate
effect for radon-induced LC,(52) the two models were equally preferred by
the BEIR VI committee.(4)”

The present study was aimed at assessing the health consequences of the
presence of radon in Quebec homes and the possible impact of various
screening programs on lung cancer mortality. Lung cancer risk due to this
radioactive gas was estimated according to the cancer risk model developed
by the Sixth Committee on Biological Effects of Ionizing Radiations.
Objective data on residential radon exposure, population mobility, and
tobacco use in the study population were integrated into a Monte-Carlo-type
model. Participation rates to radon screening programs were estimated from
published data. According to the model used, approximately 10% of deaths due
to lung cancer are attributable to residential radon exposure on a yearly
basis in Quebec. In the long term, the promotion of a universal screening
program would prevent less than one death/year on a province-wide scale (0.8
case; IC 99%: -3.6 to 5.2 cases/year), for an overall reduction of 0.19% in
radon-related mortality. Reductions in mortality due to radon by (1) the
implementation of a targeted screening program in the region with the
highest concentrations, (2) the promotion of screening on a local basis with
financial support, or (3) the realization of systematic investigations in
primary and secondary schools would increase to 1%, 14%, and 16.4%,
respectively, in the each of the populations targeted by these scenarios.
Other than the battle against tobacco use, radon screening in public
buildings thus currently appears as the most promising screening policy for
reducing radon-related lung cancer.
