Combustion and other high-temperature processes can produce solid aerosol nanoparticles
with complex morphologies, including fractal-like aggregates of primary particles …

Airborne pollutants are present all the time and everywhere in the form of gases, odors, and
particulate matter. These pollutants have an increasing influence on our daily life. In …

A comprehensive analysis of the problem of determining aerosol size distributions on the
basis of data from convnetional measuring instruments is presented. An inversion algorithm …

In the first part of the paper, the parameters of the airborne radon daughters for dose
estimation are defined. In the second part, the most important methods and techniques for …

Abstract The EM (Expectation-Maximization) algorithm is presented as a novel method of
reconstructing ultrafine particle size distributions from diffusion battery data. The algorithm is …

Wire screens are commonly used to estimate “unattached” Rn daughter fractions in ambient
and mine atmospheres. However, it is now recognized that the “unattached” fraction is in …

We report the attraction of radon daughter nuclei in normal domestic room air to everyday
sources of power frequency electromagnetic fields. TASTRAK plastic track detectors were …

A comparative study of the response of a photo-electric aerosol sensor (PAS) to different
PAH aerosol systems is presented. The photo-electric activity of pure PAH particles as well …

Only recently, the radioactive gas thoron (220Rn) and its decay products have been
regarded as significant health risk in the indoor environment. This is because of new …

Polycyclic aromatic hydrocarbons (PAHs) are a class of compounds considered to have
human carcinogenic potential and have been found associated with many respirable …
