Conference paper (peer-reviewed)abstract
- The particle size distribution in 11 different dwellings was studied during 5-7 days, samples being taken every 15 min. Large variation in the aerosol concentration has been found. Also the size distribution of the aerosol varies depending on the level of activity in the home, e.g. smoking and cooking. The average area median diameter found in the dwellings was 0.2 ,am. A technique for the measurement of radon daughter distribution on different airborne matter was developed and tested. The method is based on the use of an electrical mobility analyzer and alpha-spectrometry of the radon daughters collected on a fluoropore filter. Some results are presented and discussed.
