Radiation Measurements

Data on optically stimulated luminescence (OSL) detectors (Al2O3:C) and films irradiated at the Fondazione Policlinico Universitario ‘‘A. Gemelli’’ using a MRIdian system (ViewRay Inc., Mountain View, California, USA). The results are described in the publication Shrestha, N., Yukihara, E.G., Cusumano, D. and Placidi, L., 2020. Al2O3:C and Al2O3:C,Mg optically stimulated luminescence 2D dosimetry applied to magnetic resonance guided radiotherapy. Radiat. Meas. 138, 106439.Experimental description is provided in the associated publication.

+ One-grain experiment We measured 20 single-grain discs with one grain per disc from sample NCL-1821112, which has been bleached for 48 hours in a solar simulator prior to measurements. Please visit the Netherlands Centre for Luminescence dating (NCL) database for more information on the sample background at: https://www.lumid.nl/. On the website go to the 'projects' tab and search for NCL-code 1821. The measurement protocol, as reported in Table 1 of the manuscript, was repeated 8 times for incremental aperture steps. + Reader comparison experiment We measured 20 single-grain discs per reader all originating from NCL-1821112, which has been bleached for 48 hours in a solar simulator prior to measurements, to compare the performance of both devices. + Measurement protocols and data formats The measurement protocols were written in Riso's sequence editor software. All Riso software is downloadable at: https://www.fysik.dtu.dk/english/research/radphys/research/radiation-instruments/tl_osl_reader/software. The raw data is stored in a Riso .binx file which can be opened in Riso's analyst software environment. EMCCD generated luminescence images has been analyzed in Riso's Viewer+ software before further analyses. + Processing and analysis scripts in R All processing of data (modifications, calculations, etx) and analysis of data was performed in R. All scripts are commented. Per experiment an R script was written. + Figures and tables All figures and tables were created through R. Refer to the R scripts for detailed information within the script.
