FILTER PACK TECHNIQUE FOR CLASSIFYING RADIOACTIVE AEROSOLS BY PARTICLE SIZE. PART 1. PRELIMINARY REPORT AND EVALUATION
Technical Report
·
OSTI ID:4161612
Study of the efficiency of filters for the retention of natural airborne radioactive aerosols showed that the particles with which the radioactivity of the short-lived radon daughters is associated have greater ability to penetrate the various filter media that has the fission product debris in the atmosphere; therefore the former is associated with aerosols of smaller size. A preliminary evaluation of the techniques of employing packs of filters of different retentivity characteristics to determine the particle size and/or particle size distribution of radioactive aerosols indicated the feasibility of the method.
