Development of a self-cleaning dispersion and exposure chamber: Application to the monitoring of simulated accidents involving the generation of airborne nanoparticles

- Design of an airtight and self-cleaning chamber for dispersing hazardous matter.
- Dispersion testing in both low-particle and background-filled environments.
- Accidental release of nanosized silica analyzed in terms of source strength.
- Released nanoparticles reached a peak in the most penetrating size range.
- Stronger matter release in low-particle environments than in particle-filled media.
