“…The mean energy loss depends on the mean excitation energy [11], which has only been measured in gaseous argon. We conservatively ascribe a ∼10% uncertainty on this value to account for possible differences due to the phase also observed in other materials [14]. The wire-sensitive thickness depends on the quantity of diffusion transverse to the electric field [12].…”

“…Water has been recommended by the IAEA Code of Practice TRS-398 (Andreo et al 2000) and AAPM TG-253 (Fulkerson et al 2020) as the reference medium for the determination of the absorbed dose in kV photon beams. Therefore, in the present simulations the phantom considered was of liquid water with the composition recommended by ICRU Report 37 (Berger et al 1984) and the updated mean excitation energies and mass density given by ICRU Report 90 (Seltzer et al 2014).…”

Three different correction factors for measurements with the parallel-plate ionization chamber PTW T34013 on the Esteya electronic brachytherapy unit have been investigated. This chamber type is recommended by AAPM TG-253 for depth-dose measurements in the 69.5 kV x-ray beam generated by the Esteya unit. Monte Carlo simulations using the PENELOPE-2018 system were performed to determine the absorbed dose deposited in water and in the chamber sensitive volume at different depths with a Type A uncertainty smaller than 0.1%. Chamber-to-chamber differences have been explored performing measurements using three different chambers. The range of conical applicators available, from 10 to 30 mm in diameter, has been explored. Using a depth-independent global chamber perturbation correction factor without a shift of the effective point of measurement yielded differences between the absorbed dose to water and the corrected absorbed dose in the sensitive volume of the chamber of up to 1% and 0.6% for the 10 mm and 30 mm applicators, respectively. Calculations using a depth-dependent perturbation factor, including or excluding a shift of the effective point of measurement, resulted in depth-dose differences of about ± 0.5% or less for both applicators. The smallest depth-dose differences were obtained when a shift of the effective point of measurement was implemented, being displaced 0.4 mm towards the center of the sensitive volume of the chamber. The correction factors were obtained with combined uncertainties of 0.4% (k = 2). Uncertainties due to chamber-to-chamber differences are found to be lower than 2%. The results emphasize the relevance of carrying out detailed Monte Carlo studies for each electronic brachytherapy device and ionization chamber used for its dosimetry.
