Aerosol size distribution of the radon progeny in outdoor air And a laser aerosol spectrometer (100-5000 nm).

摘要

The activity size distribution of the short-lived radon decay products in ambient air was Measured continuously over several weeks. Two different measurement techniques were used: A direct measurement with a low-pressure on-line alpha cascade impactor (OLACI) and an Indirect determination based on measurement with a differential mobility analyser (5-200 nm)
