a Based on a submultiplicative relationship between tobacco-smoking and radon.

b Exposures are represented by concentrations in bequerels per cubic meter (Bqm-3), picocuries per liter (pCiL-1), or Working Levels (WL), assumed to be constant for home occupancy at the 70% level and 40% equilibrium between radon and its progeny, and also by joules-hours per cubic meter per year (Jhm-3/y) and Working Level Months per year (WLM/y). For definitions of these terms, see the Glossary at the end of this report.
