“…CMOS-based radon detectors that are also promising in cost reduction while retaining high sensitivity have benefited from standard low-cost CMOS foundry processes with high spatial resolution. A bunch of CMOS-based detectors [8][9][10][11] have been developed and have shown competitive performances. In these designs, 222 Rn or its progenies are collected either passively, or actively using aerosol and electrostatic concentrators, and they are detected by their emitting alpha particles.…”

In this paper, we study how pixel size influences energy resolution for a proposed pixelated detector-a high sensitivity, low cost, and real-time radon monitor based on a Topmetal-II − time projection chamber (TPC). This monitor was designed to improve spatial resolution for detecting radon alpha particles using Topmetal-II − sensors assembled by a 0.35 µm CMOS integrated circuit process. Owing to concerns that small pixel size might have the side effect of worsening energy resolution due to lower signal-to-noise ratio, a Geant4-based simulation was used to investigate the dependence of energy resolution on pixel sizes ranging from 60 µm to 600 µm. A non-monotonic trend in this region shows the combined effect of pixel size and threshold on pixels, analyzed by introducing an empirical expression. Pixel noise contributes 50 keV full-width at half-maximum energy resolution for 400 µm pixel size at 1 ∼ 4 σ threshold that is comparable to the energy resolution caused by energy fluctuations in the TPC ionization process (∼ 20 keV). The total energy resolution after combining both factors is estimated to be 54 keV for a pixel size of 400 µm at 1 ∼ 4 σ threshold. The analysis presented in this paper would help choosing suitable pixel size for future pixelated detectors.

Radon is an invisible, odorless, and chemically inactive radioactive gas produced by the decay of uranium ore. Various types of equipment and components have been proposed for use in effective radon detection. In this paper, we describe a radon detector that uses an analog CMOS image module. Based on our studies, we beli system would be helpful in protecting many people from the dangers associated with radon exposure.

Radon is an invisible, odorless, and chemically inactive radioactive gas produced by the decay of uranium ore. Various types of equipment and components have been proposed for use in effective radon detection. In this paper, we describe a radon detector that uses a PIN photodiode radon-sensor module and a Wi radon monitoring system. Based on our studies, we believe that this system would be helpful in protecting many people from the dangers associated with radon exposure.
