| Abstract: | The study group in the Railway Ministry on conversion method of relative mass concentration intomass concentration(710054) This article reports that mass concentration and telative mass concentration of airborne respirabledust,and total dust were measured at same time and Place by using dust indicator furnish with separatorconform to BMRC size classified standard and P-5L_2digital dust indieator which were put in every dustworking Place.The convension coefficient K.and K_4 for transform relative mass concentration of airborntotal dust into mass concentration conversion graph of CPM and mg/m~3 were gotten by correlationanalysis and calculation |
