Using Monte Carlo (with Geant4) and COMSOL simulations, the authors have defined a
useful tool to reproduce the alpha spectroscopy of 222Rn, 220Rn and their ionized …

The radioactive isotope 222 Rn is one of the most crucial intrinsic background sources for
experiments dealing with a low event rate. Being a noble gas, it permanently emanates from …

Abstract A Frisch-grid Ionization Chamber (FGIC) for the measurement of low activity of
alpha-particle emitters has been built. The design and performance are described in this …

The interest in the measurement of thoron (220 Rn) activity concentration in air has recently
increased, with the attention for the development of standards useful for the calibration of …

Solid-state nuclear track detectors have found wide use in various domains of science and
technology, eg in environmental experiments. The measurement of alpha activity on sources …

A CMOS active pixel sensor (APS), originally designed for the tracking of minimum ionizing
charged particles, has been used for α-particle counting inside a tank containing 1200 …

Solid-state nuclear track detectors (SSNTDs) have found wide use in various domains of
science and technology, eg. in environmental experiments. Measurement of α activity on …

This paper presents a study of the 222 Rn absorption properties of EJ-212 and BC-400
plastic scintillators (PSs). The diffusion length and the partition coefficient of 222 Rn from air …

Petroleum products and medical drugs have been studied in order to determine 238 U, 232
Th, 222 Rn, 220 Rn and their progenies contents in them using mean absolute detection …

Alpha emitters are usually identified and quantified by alpha spectrometry measurements in
a vacuum chamber performed in laboratory environments. This study shows that transuranic …
