The objective of this project was to investigate the feasibility of analytical techniques potentially capable of determining Mg, Al, Si, S, Ca, and Fe in 1- to 2-mg samples of respirable coal mine dust is that fraction of airborne dust in coal mines minutes per sample, using equipment capable of being truck mounted for field-laboratory operation. Respirable mine dust is that fraction of airborne dust in coal mines that is breathed in and retained in miners' lungs. The particle size distribution so retained is in the range of 0.1 To 5 micrometers, peaking at about 1 micrometer. The techniques investigated were a-particle scattering, neutron activation, electron excitation of characteristic x-rays (using either an electron gun or a radioisotope source), a-particle excitation of characteristic x-rays, and x-ray fluorescence with both radioisotopic and x-ray tube excitations.
