A new radon film-badge accurately measures radon in water, soil, and other media. This passive monitor shows consistent results across different labs, making it a reliable tool for environmental radon monitoring.

Area of Science:

  • Environmental Science
  • Radiological Protection
  • Analytical Chemistry

Background:

  • Radon is a naturally occurring radioactive gas that can accumulate in indoor environments and water sources.
  • Accurate measurement of radon is crucial for assessing potential health risks.
  • Existing methods for radon detection can be complex or expensive.

Purpose of the Study:

  • To introduce and evaluate a newly developed radon film-badge for measuring radon in various media.
  • To assess the performance and reliability of the film-badge for radon in water measurements.
  • To determine the inter-laboratory variability of the film-badge when using different processing and counting procedures.

Main Methods:

  • The radon film-badge was utilized to measure radon concentrations in water samples from private wells and tap water.

  • Passive monitors were distributed to various laboratories for self-construction using CR-39 detectors.
  • Monitors were calibrated in a controlled radon chamber at the National Institute of Radiation Metrology (ENEA) before inter-laboratory testing.

    • Main Results:

    • The film-badge demonstrated wide response linearity, enabling accurate radon in water measurements from 10 to ~10,000 Bq/L.
    • A mini-survey by Health Canada successfully measured radon in 12 private wells and tap water from the Ottawa River.
    • Despite variations in etching and counting procedures across laboratories, the film-badge responses showed a low variability of approximately 12%.

    Conclusions:

    • The developed radon film-badge is a versatile and effective passive monitor for measuring radon in diverse environmental samples, particularly water.
    • The monitor's consistent performance across different laboratories and procedures highlights its robustness and suitability for widespread use.
    • This technology offers a reliable and accessible method for radon monitoring, contributing to improved radiological protection and public health assessments.
