Abstract : A system for identifying chrysotile asbestos as well as other asbestiform fibers in air pollution samples which comprises a collimated x-ray beam which is incident on parallel aligned asbestos fibers. Diffracted x-rays are detected by a proportional counter set at the diffraction line position for the (002) plane. Background intensity may be detected by a second counter set above the axis, or the sample may be rotated 90 deg and the one detector used to detect diffracted and background x-rays. (Author)
