Summary

This study shows that optically stimulated luminescence (OSL) can measure dose-depth profiles in concrete. Even poorly zeroed concrete samples yield useful data for accident dose assessment.

Area of Science:

  • Geoscience
  • Materials Science
  • Radiation Dosimetry

Background:

  • Retrospective dosimetry often uses heated building materials like ceramics.
  • Unfired materials, such as concrete, are common but their initial dose is often unknown.
  • Accurate dose assessment in unfired materials is crucial for industrial safety.

Purpose of the Study:

  • To investigate the feasibility of using optically stimulated luminescence (OSL) for retrospective dosimetry in concrete.
  • To measure dose-depth profiles in new concrete samples after laboratory irradiation.
  • To assess the effectiveness of OSL on individual quartz grains from concrete.

Main Methods:

  • Optically stimulated luminescence (OSL) measurements were performed on a new concrete brick.

Related Experiment Videos

  • A known dose was applied to the concrete sample in a laboratory setting.
  • Dose distribution was analyzed using small aliquots (65 quartz grains) and single quartz grains extracted from the concrete.

    • Main Results:

    • OSL successfully measured a dose-depth profile in the concrete brick.
    • Both aliquot and single-grain analyses provided satisfactory results.
    • Useful dose information was obtained despite the concrete being poorly zeroed before irradiation.

    Conclusions:

    • Single-grain OSL analysis is a viable method for retrospective dosimetry in poorly zeroed building materials like concrete.
    • This technique can provide valuable data for assessing accidental radiation doses in industrial environments.
    • Further research can refine OSL application for unfired construction materials.
