Using the optically stimulated luminescence technique for one- and two-dimensional dose mapping: a brief review

Area of Science:

• Medical Physics
• Radiation Detection and Measurement

Background:

• Traditional dosimetry methods like films and diode arrays have limitations in precision and spatial resolution for dose distribution verification.
• Radiological and radiochromic films suffer from production variability, impacting result precision.
• Ionization chamber and diode arrays often lack the necessary spatial resolution for detailed dose mapping.

Purpose of the Study:

• To provide a comprehensive overview of optically stimulated luminescence detectors (OSLDs) for one-dimensional (1D) and two-dimensional (2D) dose mapping.
• To review the principles, materials, and applications of OSLDs in assessing radiation dose distribution.
• To synthesize findings from scientific literature published between 1998 and 2021 on OSLD dose mapping.

Main Methods:

• Systematic review of international scientific literature from 1998 to 2021 focusing on OSLD applications in dose mapping.
• Categorization of research findings based on OSL material type (e.g., film, ceramic plate/BeO).
• Analysis of key characteristics, principal findings, and developments in OSLD film production and reader assembly.

Main Results:

• OSLDs, in film or ceramic plate (BeO) form, demonstrate significant potential for 1D and 2D dose mapping applications.
• The review details various OSL materials and their specific uses in dose distribution assessment.
• Key studies highlight advancements in OSLD film production and reader technology.

Conclusions:

• OSLDs present a viable and advancing technology for precise dose distribution verification in radiation dosimetry.
