Area of Science:

• Materials Science
• Radiation Physics
• Analytical Chemistry

Background:

• Silver ion-activated phosphate glass (Ag+-glass) shows promise for radiation detection.
• Its multifunctional properties are key to its potential as a detector.

Purpose of the Study:

• To explore the potential of Ag+-glass for radiation dosimetry.
• To investigate the combination of its independent signals for enhanced measurement capabilities.

Main Methods:

• Utilizing radiophotoluminescence, optical absorption, and nuclear track signals from Ag+-glass.
• Analyzing the combined data to determine dose and linear energy transfer.

Main Results:

• Ag+-glass provides three independent detection signals.
• The combination of these signals significantly widens the measurable dynamic range for both dose (10 μGy-10 kGy) and linear energy transfer (<10 keV/μm and >1 MeV/μm).

Conclusions:

• Ag+-glass is a promising material for radiation dosimetry.
• Its multifunctional detection capabilities allow for accurate measurements in diverse radiation fields over an extended dynamic range.
