a Model used in the model to compute PC=0.5, RR = 1 + ß × d × Ýyfe × tsle × age × t(age - 60) with time since last exposure, and year first exposed defined by categories. For calculations, in Table 2 is replaced by ×exp[1.64×SE( ß)] then adjusted to ßsmk or ß ns as described in the text. For computing RR with age categories, mean ages 44.5, 54.8, 63.9, and 75.7 used.

b A value of 0.0 years exposed denotes exposure to radon progeny which is less than 0.05 years (or 0.6 mos = 0.05×12, or 102 working hrs = 170×0.6)
