Quantitative assessment of the absorbed dose in cryodeposited noble-gas films under X-ray irradiation: Simulation vs. experiment

An EPR study on the radiolysis of isolated ethanol molecules in solid argon and xenon: matrix control of radiation-induced generation of radicals in cryogenic media

“…20 keV). Basically, the absorbed dose rate in xenon for the actual X-ray spectrum used in this work is higher than that in argon because of the difference in the X-ray absorption coefficients for Ar and Xe (the ratio depends on the sample thickness 36 ). However, it should be noted that the shape and thickness of the sample in our experimental configuration may vary from experiment to experiment, which causes considerable uncertainty in the average absorbed dose rate (up to a factor of 1.5).…”

Formation and Evolution of H2C3O+•Radical Cations: A Computational and Matrix Isolation Study

“…20 keV). The absorbed dose rate in the noble gas matrix samples was estimated in our earlier work 75 by using data from a calibrated Fricke dosimeter and Geant4 calculations of ratios of the absorbed dose rate in the 80 μm Ar matrix to that in the dosimeter. The value of the absorbed dose rates in an Ar matrix is 38.6 Gy s −1 (in the cryostat used for FTIR experiments).…”

Reactions of oxygen atoms with fluoroform and its radiolysis products: matrix isolation and ab initio study

“…The absorbed dose rate for the samples was evaluated using the Fricke dosimeter and Monte–Carlo simulations; the details are given elsewhere. 37 The estimated absorbed dose rates for Ar, Kr and Xe matrices were approximately 36.0–41.9, 64.7–83.3 and 48.6–63.9 Gy s −1 , respectively. Photolysis of samples was carried out by a P-1532hoz low-pressure mercury lamp with a synthetic quartz tube through a MgF 2 cryostat window.…”
