Implication

Experimental evaluation of collection efficiency in radon and thoron environments highlights the importance of temperature and voltage in monitoring applications.

Key Points

This research aims to understand how temperature and voltage affect the electrostatic collection efficiency for radon and thoron progeny in various chamber designs.
Conducted experiments in a reference and large hemispherical chamber under controlled radon and thoron atmospheres, N=...
Evaluated electrostatic collection efficiency as a function of applied high voltage and temperature with varying configurations.
Analyzed the impact of diffusion barriers on collection efficiency for both types of progeny.
Collection efficiency increased with applied voltage for both 218 Po and 216 Po with confirmed electric field strength effects.
For 216 Po, different trends were observed based on the presence of the diffusion barrier.
218 Po displayed a U-shaped dependence, showing a minimum at intermediate temperatures, influenced by ion transport and decay losses.
