Measurement of the mass concentration of airborne dust in coal mines by light-scattering

Journal of Aerosol Science, 1973
Abstract The paper presents calculations of the scattered-light intensities, at various angles, for clouds of spheres of the materials found in the dust in coal mines. These calculations predict that an angle exists at which the light scattered per unit mass concentration is equal for clouds of coal particles and of limestone particles, and that this
