Radioluminographic Monitoring of Radioactive Surface Contamination on a Rough Surface Material.

Two-dimensional halide perovskite as β-ray scintillator for nuclear radiation monitoring

“…Figure 5b displays the long-term stability under continuous β-ray irradiation with an accumulated dose reaching up to 10 kGy (dose rate 0.67 kGy h −1 ). This radiation dose is >10 6 times larger than that in brain computed tomography (CT, typically~8.6 mSv per time by X-ray). The result unambiguously confirms that the STA 2 PbBr 4 :Mn is able to offer a persistent scintillation performance, corroborating a robust scintillation behavior.…”

“…Nuclear reaction mainly releases four types of high-energy rays: α-ray, β-ray, γ-ray, and neutron ray. Among them, β-ray with a moderate penetrating power is an important signal for surface radiative contamination surveillance 6,7 . In general, scintillatorbased detectors that convert high-energy rays into visible light are facile, efficient, and cost-effective, hence are widely used for radiation detection.…”

Recent advances in radiation detection technologies enabled by metal-halide perovskites

“…Holding the moderate penetration ability, beta-ray, usually consisting of electrons or positrons, plays an important role in surface radiative contamination surveillance 103 and cancer cell treatment 104 . Beta particles can interact with atoms in the ways of elastic scattering and inelastic scattering.…”

“…Likewise, β-rays have comparatively moderate penetration power and have been used for surface radiative contamination surveillance. [113] High energy radiation-based detection/imaging approaches are of two types: a) Indirect conversion via scintillators b) Direct conversion of X-ray photons into electrical current X-ray detectors based on semiconductors operate like visible light photodetectors with some differences like photon absorption, charge generation and charge extraction processes. X-ray photons have much stronger penetration power, therefore thicker active layer of semiconductor is required, and charges are generated in the entire thickness of the semiconductor crystals.…”
