Surface charge accumulation of particles containing radionuclides in open air [PDF]

Journal of Environmental Radioactivity, 2015
Radioactivity can induce charge accumulation on radioactive particles. However, electrostatic interactions caused by radioactivity are typically neglected in transport modeling of radioactive plumes because it is assumed that ionizing radiation leads to charge neutralization.

Decay of Electric Charge on Corona Charged Polyethylene

, 2007
In this paper, the surface potential decay of corona-charged low density polyethylene (LDPE) films has been investigated. It has been found that for the same sample thickness the faster decay occurs in the sample with a higher charging voltage.

Review of Streamer Dynamics and Surface Charge Accumulation on Ice Surfaces

Electrical and Electronic Engineering, 2013
This paper rev iews the main contributions of the CIGELE research team to the dynamics of streamer d ischarges along ice surfaces. These investigations were main ly performed under lightning impulse voltage, in at mospheric air. High-speed streak photography techniques were used to observe the streamers propagating between a rod-plane configuration ...
