摘　　要：本文应用寿命表法,从各人接触石棉尘的程度计算了石棉肺的累计发病率.通过建立曲线方程,可以估算出工人工作30年,发病率在5％时,接触石棉尘不得超过3mg/m^3。The cumulative incidence rate of asbestosis was calculated from the individual dust exposures using life-table method. By establishing the curve equation, it might be estimated that the concentration of asbestos dust should not exceed 3mg/m3 when the exposure duration was 30 years with an incidence rate 5%,
