Influence of the simultaneous calibration of multiple ring dosimeters on the individual absorbed dose

Ring dosimeters for personal dosimetry are calibrated in accredited laboratories following ISO
4037-3 guidelines. The simultaneous irradiation of multiple dosimeters 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
to increase the uncertainty of ##IMG##

(Thermo Scientific) ring dosimeters with beam qualities: N-30, N-80 and N-300. Results show that the
absorbed dose in each dosimeter is compatible with each of the others and with the reference
simulation (a single dosimeter), with a coverage probability of 95% ( k = 2). Comparison with
experimental data yielded consistent results with the sa...
