Estimating past exposure to indoor radon from household glass.

摘要: CR-39 plastic was attached to household glass objects learn whether residual radioactivity from radon decay products could be measured and correlated with cumulative exposures over defined time periods. Such an approach used increase the completeness of exposure data collected in epidemiologic studies residential radon. Inability estimate concentrations for all residences adversely effects statistical power thus ability detect effect on lung cancer risk. A feasibility study performed determine if affixing surface monitors selected glass, ceramic, or enameled provided comparable estimates past those obtained year-long ambient alpha track-etch measurements. The measurements activity (R2 = 0.48) that reliable information history age objects. This technique has now been incorporated into more fully indoor
