Measurement of 222 Rn by absorption in plastic scintillators and alpha/beta pulse shape discrimination

Effects of the photocathode non-uniformity on radon measurements by plastic scintillation spectrometry

“…One of the isotopes of the radioactive noble gas radon, namely 222 Rn, is well suited for characterizing both the pulse-shape discrimination (PSD) properties and energy resolution of plastic scintillators (PSs) [4,5]. It has a 3.8 days half-life and it decays by alpha decay.…”

Partition Coefficients and Diffusion Lengths of 222Rn in Some Polymers at Different Temperatures

“…These methods use the polycarbonate as a passive sampler that absorbs and concentrates the RNG from the ambient media. Some of these methods measure the cumulative activity of the absorbed radon relying on the track-etched properties of the Makrofol DE or another (external) track detector [19,20,21], while others register the alpha-, beta- or gamma-particles of the absorbed radon and its SLP (or other RNG) by active detectors—Liquid Scintillation (LS) counters, gross alpha/beta counters, HPGe gamma-spectrometers and others (see [22,23,24,25] and the references there). To apply these methods, the temperature dependence of the diffusion properties of the polycarbonates should be known.…”

Development of a New System for Real-Time Detection of Radon Using Scintillating Optical Fibers

“…Few works have been published where fiber optics are used for the specific detection of radon either as an optic guide [8], or as the sensor probe constructed from glass fibers through radiation induced attenuation [9], or through scintillation [10,11]. The use of polymeric scintillation fibers for this specific application is still scarce but promising [12]. Polymeric scintillation fibers present a large fiber cross-section, facilitating alignment between the fiber and other optic components, increasing the system robustness.…”
