Evaluation of submicron particle size classification and collection techniques for nuclear facility off-gas streams

The present state-of-the-art in submicron aerosol size classification and collection is evaluated. Electrostatic precipitation, cryogenic collection, cascade impaction, and granular bed filtration are examined as collection methods. Methods of aerosol size classification reviewed are: electrical aerosol size analysis and the diffusion battery. An integrated sampler that includes the methods of collection and classification selected, the electrofluidized bed and the dffusion battery, is proposed and development plan presented
