Area of Science:

  • Medical Physics
  • Radiation Detection and Measurement

Background:

  • High-dose dosimetry is crucial for radiation therapy and industrial applications.
  • Existing dosimetry solutions may have limitations in range, accuracy, or cost for high-energy photons.

Purpose of the Study:

  • To introduce and validate a new high-range TLD dosemeter developed by Global Dosimetry Solutions Inc.
  • To establish correction factors for various X-ray and beta sources up to 1 KGy.
  • To assess the performance and suitability of TLD-100 and TLD-700 chips for high-dose measurements.

Main Methods:

  • Development of a high-range TLD dosemeter using TLD-100 and TLD-700 chips.
  • Determination of supralinearity correction factors for doses up to 1 KGy.
  • Testing with 10 different X-ray and beta sources, with energies ranging from 500 to 1000 Gy.

Main Results:

  • The TLD dosemeter is capable of measuring high-energy photon doses up to 1 KGy.
  • Correction factors have been established for multiple X-ray and beta sources.
  • Preliminary data suggests the need for further statistical analysis between 0.5 and 1.0 KGy.

Conclusions:

  • The developed TLD dosemeter offers a cost-effective solution for high-dose monitoring.
  • The dosimeter provides rapid data analysis, with results typically available within 24 hours.
  • Further testing is required to refine accuracy at the upper dose range, and the dosimeters are recommended for single use due to high-dose residuals.
