TLD reader with photon counting and dc techniques for wide range radiation dose measurement

Area of Science:

• Medical Physics
• Radiation Protection
• Dosimetry

Background:

• Thermoluminescent Dosimetry (TLD) is crucial for accurate radiation dose assessment.
• Existing TLD readers have limitations in sensitivity and precision for certain applications.

Purpose of the Study:

• To develop and present a novel TLD reader for precise radiation dose measurements.
• To cater to applications in radiation protection and medical physics.

Main Methods:

• The TLD reader integrates photon counting and DC methods.
• It features a reproducible heating programmer, glow curve output, digital dose display, and data processing capabilities.

Main Results:

• The reader achieves radiation dose measurements in the range of 10(-6) Gy to 100 Gy.
• Precision is approximately +/- 6% (1 sigma) at 10(-5) Gy and better than +/- 2% (1 sigma) for doses >= 0.5 cGy.
• Further enhancements aim to extend measurements down to 10(-7) Gy.

Conclusions:

• The developed TLD reader offers high precision and a wide dynamic range for radiation dosimetry.
• Its design facilitates easy operation and maintenance, making it valuable for radiation protection and medical physics.
• Ongoing improvements promise even greater sensitivity for low-dose measurements.
