LIBS in a low temperature plasma for the detection of airborne asbestos Open
Forbidden in french constructions since 1997, asbestos remains present in most of the buildings constructed before this date. Thus, during work or in case of degradation, asbestos fibres can be emitted in air. The smaller the asbestos part…
