This study introduces a modified integral counting method for accurate radon-222 (222Rn) and its daughter disintegration rate measurements using liquid scintillation. The new method corrects for soft beta-emitters and unexpected luminescence, improving accuracy over conventional techniques.

Area of Science:

  • Radiochemistry
  • Analytical Chemistry
  • Nuclear Physics

Context:

  • Accurate determination of disintegration rates is crucial for environmental monitoring and nuclear science.
  • Conventional liquid scintillation counting methods face challenges with soft beta-emitters and quenching effects.
  • Radon-222 (222Rn) and its decay products are significant radiological contaminants in natural waters.

Purpose:

  • To develop and validate a modified integral counting method for precise disintegration rate measurements of 222Rn and its daughters.
  • To overcome limitations of traditional integral counting, particularly for soft beta-emitters and in the presence of quenching.
  • To investigate and correct for unexpected phenomena observed during liquid scintillation counting of 222Rn.

Summary:

  • A modified integral counting method was developed, extrapolating to zero detection threshold to accurately measure disintegration rates of 222Rn and its daughters in natural water.
  • This method demonstrates superior accuracy compared to conventional integral counting and efficiency tracing, effectively handling soft beta-emitters and quenching.
  • The study also addresses air luminescence and temperature-dependent spectral shifts in liquid scintillators, proposing correction and calibration methods.

    • Impact:

    • Provides a more accurate and reliable method for quantifying radon isotopes in environmental samples.
    • Enhances the understanding of liquid scintillation spectrometry, particularly concerning soft beta-emitters and luminescence phenomena.
    • Contributes to improved radiological monitoring and risk assessment related to radon exposure.
