This work presents a comprehensive study of dose rate effects on Ag-doped metaphosphate glass radiophotoluminescent (RPL) dosimeters for doses ranging bewteen 1 Gy and 100 MGy. Data from multiple irradiation campaigns with diverse radiation fields, such as 60Co gamma radiation, X-rays with energy spectrum up to 100 keV, monoenergetic electron beams, and mixed fields offer valuable insights for accurate dosimetry in high-radiation environments. Dose rates ranging over 8 decades, from 0.1 kGy/h to 18 MGy/h are experimentally tested. Low dose rate effects can be observed at low doses; however, for doses higher than 100 kGy, both overestimation and underestimation can occur depending on the dose rate.

Abstract
This work presents a comprehensive study of dose rate effects on Ag-doped metaphosphate glass radiophotoluminescent (RPL) dosimeters for doses ranging bewteen 1 Gy and 100 MGy. Data from multiple irradiation campaigns with diverse radiation fields, such as 60Co gamma radiation, X-rays with energy spectrum up to 100 keV, monoenergetic electron beams, and mixed fields offer valuable insights for accurate dosimetry in high-radiation environments. Dose rates ranging over 8 decades, from 0.1 kGy/h to 18 MGy/h are experimentally tested. Low dose rate effects can be observed at low doses; however, for doses higher than 100 kGy, both overestimation and underestimation can occur depending on the dose rate.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
