Emission chambers, a method for nanosafety

Abstract : Determining the risk of exposure to nanomaterial inhalation at a workstation is a complex process. Many questions beg for answers, in particular concerning the source of the particles. What precisely is the source? Are there multiple sources? How do you distinguish the sources and measure background noise? How does the source work, and in particular, when and for what reasons does this source start emitting particles? What are the physical and chemical properties of the particles? What kinds of quantities are emitted? In view of answering such questions, industrial hygiene researchers and engineers require further information and data. Measures may be taken on site, and studies carried out in the lab. For the latter, the emission chamber is a high-performance tool that may be used under specific conditions.
