The Remote Detection of Alpha-Radioactive Nucleus Decay

Abstract

Abstract:Results of the new device design for the alpha-radiation remote detection are presented. Negative ions from the alpha particle tracks are detected by the discharge wire counter opened to air. Ion clusters being transferred from the particle tracks to the detector volume by an air flux. The detector works in a counting mode that provides sharp selectivity and accuracy of measurements. The basic parameters of the device are: detecting distance -0.5 m; measurement time -30 s; the square sensitivity -0.05 Bq/cm 2 .

New Aeroion Model of a Dangerous Natural Phenomenon—Ball Lightning

“…An important feature of light negative "oxygen" aero ions is their lifetime, which can be up to 10 minutes. This feature makes it possible, for example, to remotely register alpha particles with a high-voltage discharge detector open to the air (Gurkovskiy et al, 2015). Aero ions are conditionally divided into three groups according to their mobility in electric fields:…”

New technology and devices for fast remote detection of alpha and beta radiоaсtive contamination

“…Reading electronics (4) provides the generation and calculation of output pulse signals. The operation of the detector in counting mode provides a number of advantages over the ion current measurement mode, namely: greater selectivity against the background of other types of ionization, greater sensitivity and a rapid response to the excess of the radioactive background [10]. Figure 2 shows the mechanisms of the formation of pulses in the counter from ion clusters inherent in alpha ionization and distributed beta ionization.…”
