| Summary: | 10[]m AD particle over the previously noted range of free 900 CAM prototype manufactured by EG&G. Results show that 95%. The aspiration efficiencies varied from 80% to 106% for ability of sampler to properly signal an alarm, this study AD and a penetration of 88% for 10 m AD aerosol particles aerosol particles from the workplace. Wind tunnel testing aerosol sampler systems as affected by variations in particle and that FASs yield data that accurately characterize the aspiration efficiency of aerosol was typically greater than be minimal for the Cams to provide prompt and reliable alarms characteristics have a significant role in determining the emissions. Recognizing that the particle sampling highest. A FAS has been developed for sampling radionuclide information for both compliance and liability functions. It internal walls of the inlet-elbow probe and about 10% in the is very important that aerosol losses in the sampling systems it is operated at flow rate of 84.9 L/min in a free stream mandatory requirement. US DOE facilities generally require Monitoring radionuclide effluents has historically been only 12% of 10 []m aerodynamic diameter (AD) aerosol particles at the EL-900 take place primarily in the center of particles penetrate through the complete sampling system when recognized as an important operational activity and a sampler (AS) be installed to provide emissions quantification size and sampler flow rate. The results presented deal with stream velocities and inlet orientations. that a continuous air monitor (CAM) instrument be installed the aerosol sampling aspects of an overall sampling system, the filter, where the counting efficiency of the detector is to provide an alarm for safety purposes, and that a fixed air transport line. The EL-900 has a cutpoint larger than 20 []m velocities, sampling flow rates and particle sizes, the velocity of 9 m/s. About 88% of the losses occurred on the was conducted to characterize the collection efficiency of was oriented at O' over various ranges of free stream was used to verify sampling performance. When the sampler when operated at 84.9 L/min. Deposition of 10 []m AD aerosol which consists of an inlet-elbow, a transport line, and a EL- |
