A Device for the Remote Detection of Alpha Emitters under Field Conditions

Abstract

The portable Ñéê device was designed for the ecological monitoring of the radiation of alpha radioactive nuclides, such as plutonium, uranium, radium, etc. Under field conditions, it can detect alpha emitters at distances of up to 0.5 m. The device's performance data are as follows: the lower threshold of the particle energy is 0.2 MeV, single measurement time is no more than 10 s, and the minimum detectable activity is 1000 Bq.

The Remote Detection of Alpha-Radioactive Nucleus Decay

“…Output signals from amplifier connected with ion counter are presented in Figure 2. One can see two groups of short discharge pulses which are created by ion clusters [1]. …”

Long-distance detection of alpha-radioactivity: Method and device

“…The detector works in air in the counting mode that provides sharp selectivity and high accuracy of measurements (Simakov et al, 1999;Simakov, 2005;Charpak et al, 2008;Charpak et al, 2011). Fig.…”
