[P162] Postal TLD dosimetry audits in radiotherapy in poland – Results of 2017

Characterization of passive dosimeters in proton pencil beam scanning – A EURADOS intercomparison for mailed dosimetry audits in proton therapy centres

“…Although auditing programs are predominantly based on TLDs [1,10], alanine is considered to be more attractive in comparison to TLDs for several reasons including intrinsic tissue equivalency, weak energy dependence, dose rate independence and low fading [11]. In the past, some national audit programs have used alanine and/or TLD powder such as in Italy [4], Belgium [5], Poland or Czech Republic [12,13]. While the successful introduction and development of carbon doped aluminium oxide (Al 2 O 3 :C) for optically stimulated luminescence detectors (OSLDs) has led to its routine use as a passive personal dosimeter, its use in radiotherapy dosimetry is still not broadly applied [14].…”
