Pe =exponent of the excess risk function;A0 =standard age at first exposure; L=standard duration of exposure;Y0 =first year of occupational exposure to asbestos; Y1 =year that the rate of increase of the mean exposure concentration per generation began to accelerate (see fig 3);λ=ratio of the mean exposure concentration for the generation that began working in the yearY1 and the concentration for the most exposed generation (Emax );Y2 =year that the first of the most exposed generations began working;Y3 =year that the last of the most exposed generations began working.
