A study was conducted to evaluate two instantaneous-reading dust monitors that utilize the attenuation of beta rays to determine respirable mass-dust concentrations. The one monitor utilizes impaction to deposit the sample on a mylar substrate while the other monitor collects the sample on a glass fiber filter. Measurements obtained using test aerosols of coal, limestone, and silica dusts were compared to measurements obtained with the approved personal coal mine dust sampler. Instrument linearity was synthetically checked using mylar and formvar films of varying thickness. The monitor employing the glass fiber filters was also tested in underground coal mines.
