    Ring dosemeters for personal dosimetry are calibrated in accredited laboratories following ISO 4037-3 guidelines. Multiple irradiation of dosemeters would save time, but has to be carefully studied, since the scattering conditions could change and influence the absorbed dose in nearby dosimeters. Monte Carlo simulations using PENELOPE-2014 were performed to explore the need of increasing the uncertainty of Hp(0.07) in the simultaneous irradiation of three and five DXT-RAD 707H-2 (Thermo Scientific) ring dosemeters with beam qualities: N-30, N-80 and N-300. Results show that the absorbed dose in each dosemeter is compatible with each other and with the reference simulation (a single dosemeter) with a coverage probability of 95% (k = 2). Comparison with experimental data yielded consistent results with the same coverage probability. Therefore, five ring dosemeters can be simultaneously irradiated with beam qualities ranging, at least, between, N-30 and N-300 with a negligible impact on the uncertainty of Hp(0.07). © 2021 Society for Radiological Protection.
