Electron Paramagnetic Resonance (EPR) dose reconstruction in dog calcified tissues reveals significant internal radiation dose variations from strontium-90 (90Sr) exposure. Dentine and specific bone areas are key biomarkers for post-mortem dose assessment.

Area of Science:

  • Radiological Physics
  • Biomedical Sciences
  • Toxicology

Background:

  • Internal exposure to radionuclides like strontium-90 (90Sr) poses significant health risks.
  • Accurate dose reconstruction is crucial for understanding radiation effects and for forensic applications.
  • Calcified tissues offer potential for retrospective dosimetry due to their long-term retention of incorporated radionuclides.

Purpose of the Study:

  • To present the results of Electron Paramagnetic Resonance (EPR) dose reconstruction in the calcified tissues of dogs internally exposed to 90Sr.
  • To evaluate the reliability of different calcified tissues as biomarkers for retrospective dosimetry of 90Sr.
  • To compare EPR-reconstructed doses with direct measurements.

Main Methods:

  • Internal exposure of dogs to 90Sr.

  • Sample collection of various calcified tissues (teeth, femur, vertebrae).
  • Electron Paramagnetic Resonance (EPR) spectroscopy for dose reconstruction in calcified tissues.
  • Comparison with alanine dosimeter measurements.

    • Main Results:

    • Significant differences in absorbed doses were observed in non-symmetric tooth positions, unlike symmetric ones.
    • Crown dentine absorbed doses comparable to femur cortical bone, endosteal surface, and fatty marrow, indicating predominant internal exposure.
    • Metaphyseal trabecular femur, alveolar bone walls, and vertebral bone showed the highest absorbed doses, identifying them as potential biomarkers.
    • Satisfactory correlation found between EPR-reconstructed doses in calcified tissues and alanine dosimeter measurements.

    Conclusions:

    • EPR retrospective dosimetry using calcified tissues is a valuable method for assessing internal 90Sr exposure.
    • Specific bone and tooth structures serve as reliable biomarkers for post-mortem dose reconstruction.
    • The findings support the utility of EPR dosimetry for internal contamination assessment in forensic and research settings.
