Abstract(s)
The aim of this study was to evaluate the occupational exposure of metal (aluminum, steel and titanium) cleaning with two types of LASERS (Laboratory Ablation LASER (LAL) and Diode) incisions with different intensities, different speeds, different incision times and different distances between lines in the samples, in order to be able to compare the resulting emissions for the different operative conditions. It is concluded that the number of nanoparticles measured with the probes inside the extraction are generally higher for all types of materials processed during this study; and that the number of nanoparticles are larger when compared with the number of nanoparticles released at the typical occupational level. The type of laser in question, its intensity, speed, incision time and line spacing affect the release of nanoparticles both in terms of the total number of nanoparticles released and in their size.
