Respirable crystalline silica is created when cutting, sawing, grinding, drilling, and crushing stone, rock, concrete, brick, block, and mortar. Activities such as abrasive blasting with sand; sawing brick or concrete; sanding or drilling into concrete walls; grinding mortar; manufacturing brick, concrete blocks, stone countertops, or ceramic products; and cutting or crushing stone. Worker exposures to respirable crystalline silica dust pose a carcinogenic threat at concentrations as low as 50 µg/m 3. J3’s use of the PANalytical CubiX³ high-performance industrial diffractometer in combination with the Bragg-Brentano HD optics module enables fast and reliable analysis of respirable silica measurements, down to 1 µg/m 3.
