title: [Lung cancer risk and passive smoking: quantitative aspects].
abstract: The exposure of passive smokers is estimated equivalent to 1/10-1 cig./day actively smoked. According to the relationship of dose and time (ref. 4) lung cancer incidence figures are calculated for ages 40, 50, 60, 70 and 79 years of age and further relative risks in relation to non smokers. Risks of smokers with a daily consumption of 1/10-1 cig. are in the range of R = 1.03-1.36. Analogously applied to passive smokers this range of exposure can be neglected because it has no major effect on lung cancer incidence. The results of three studies about passive smoking and lung cancer (ref. 5, 7, 18) are compared with the calculated risks and differences discussed.
