    Airborne particulate matter has been counted in the size range of 0.32 μ to 8 μ by means of the scattered-light technique. Dust levels in a variety of typical work areas employed in electronic device development and manufacture are reported with a description of some of the factors contributing to these levels. Other measurements relate dust counts to the number of personnel and their activity, to changes in personnel levels during a 24-hr period, to filtering methods employed to remove dust, and work-hood design. A comparison is made of these counts with counts obtained by the petri dish method, which counts are indirectly similar, and with the proposed ASTM referee method.
