Real time particle fallout monitor with tubular structure - High …

An apparatus for monitoring particle fallout incorporates a particle flux monitor and a tubular structure. The tubular structure is positioned over an aperture in the housing of the monitor to provide a still air condition so that the particles that descend to the monitor and pass through the light net of the monitor are precluded from being carried back to the light net, which would result in an erroneous count.
