    Rapid Electrochemical Detection of Radiolysis Products in an Aqueous Solution Exposed to Alpha Particle Beams by J. E. Liedhegner, W. Jennings, J. Wainright

    Published 2011-01-01
    “…An electrochemical cell has been developed that allows for the rapid and exhaustive detection of oxygen and/or hydrogen peroxide produced during the radiolysis of aqueous solutions by alpha particle or proton beams. Short, 10–100 s, exposures were sufficient to yield steady-state electrochemical currents proportional to the radiolysis G-factor. …”

    Evaluation of Antimony Tri-Iodide Crystals for Radiation Detectors by Toshiyuki Onodera, Koei Baba, Keitaro Hitomi

    Published 2018-01-01
    “…SbI3 detectors with a simple planar structure were fabricated using the cleavage plates of the grown crystals, and the pulse-height spectra were recorded at room temperature using an 241Am alpha-particle (5.48 MeV) source. The detector showed response to the alpha-particle radiation.…”

    Using intermediate energy knockout, pickup, and charge exchange reactions with invariant mass spectroscopy for investigating nuclear structure beyond the proton drip line by L. G. Sobotka, L. G. Sobotka, R. J. Charity

    Published 2025-01-01
    “…Unlike binary alpha decay, the part of the Chart of the Nuclides this mini review will focus on can undergo decay into many-particle final states and invariant-mass spectroscopy is the frame-invariant and multi-particle replacement for simple binary alpha-particle spectroscopy. Here we highlight how pairing is reflected in the zig-zaggy pattern of the drip line, the decay of nuclides beyond the drip lines, and what the masses of nuclides exterior to the p-drip line have taught us about shell structure. …”

    From DNA Radiation Damage to Cell Death: Theoretical Approaches by Francesca Ballarini

    Published 2010-01-01
    “…Furthermore, a mechanistic model developed at the University of Pavia and based on the relationship between cell inactivation and chromosome aberrations was presented, together with recent results; the good agreement between model predictions and literature experimental data on different radiation types (photons, protons, alpha particles, and Carbon ions) supported the idea that asymmetric chromosome aberrations like dicentrics and rings play a fundamental role for cell death. …”

    Comparison of ZnS(Ag) Scintillator and Proportional Counter Tube for Alpha Detection in Thin-Layer Chromatography by Marc Pretze, Jan Wendrich, Holger Hartmann, Robert Freudenberg, Ralph A. Bundschuh, Jörg Kotzerke, Enrico Michler

    Published 2024-12-01
    “…(1) <b>Background</b>: Targeted alpha therapy is an emerging field in nuclear medicine driven by two advantages: overcoming resistance in cancer-suffering patients to beta therapies and the practical application of lower activities of <sup>212</sup>Pb- and <sup>225</sup>Ac-labelled peptides to achieve the same doses compared to beta therapy due to the highly cytotoxic nature of alpha particles. However, quality control of the <sup>212</sup>Pb/<sup>225</sup>Ac-radiopharmaceuticals remains a challenge due to the low activity levels used for therapy (100 kBq/kg) and the formation of several free daughter nuclides immediately after the formulation of patient doses; (2) <b>Methods</b>: The routine alpha detection on thin-layer chromatograms (TLC) of <sup>212</sup>Pb- and <sup>225</sup>Ac-labelled peptides using a MiniScanPRO+ scanner combined with an alpha detector head was compared with detection using an AR-2000 scanner equipped with an open proportional counter tube. …”
