Interpretation of Data from the Screen-Type Diffusion Battery with the Sequential Arrangement of Trapping Elements

摘要

The screen-type diffusion battery developed by the Institute of Industrial Ecology is described. The battery is characterized by a sequential arrangement of trapping elements made of woven metal nets. The instrument has been designed to assess the particulate composition of the environment by the content of short-lived decay products of radon. The simulation results are presented together with the interpretation of data of a real experiment, in which a three-modal distribution with median diameters in the ranges of 1-2, 3-4, and 19-20 nm, has been obtained.
