Passive diffusion samplers can measure both tritium (HTO) and carbon-14 (14CO2) in the air simultaneously. These samplers, originally for HTO, are effective for 14CO2 monitoring with a slightly lower sampling rate.

Area of Science:

  • Environmental monitoring
  • Radiological protection
  • Analytical chemistry

Background:

  • Tritium (HTO) and carbon-14 (14CO2) are common airborne radioactive contaminants.
  • Passive diffusion samplers are utilized for monitoring HTO in air at CANDU facilities.
  • Evaluating the capability of existing samplers for other radionuclides is crucial for comprehensive monitoring.

Purpose of the Study:

  • To assess the suitability of passive diffusion samplers for measuring 14CO2 in air.
  • To determine the sampling rate of 14CO2 relative to HTO.
  • To confirm the simultaneous measurement capability for both HTO and 14CO2.

Main Methods:

  • Controlled environmental exposures were conducted using HTO-in-air and 14CO2-in-air.
  • Passive diffusion samplers were exposed to single and mixed gas atmospheres.

  • Sampling rates were determined and compared based on diffusion coefficients.

    • Main Results:

    • The sampling rate for 14CO2-in-air was approximately 0.7 times that of HTO-in-air.
    • This observed ratio aligns with theoretical calculations based on gas diffusion coefficients.
    • Samplers demonstrated effectiveness for simultaneous HTO and 14CO2 measurement.

    Conclusions:

    • Passive diffusion samplers are suitable for measuring both HTO and 14CO2 in air.
    • Existing HTO samplers can be adapted for dual-radionuclide monitoring with appropriate solutions.
    • This enhances the capability for comprehensive airborne radioactivity assessment at nuclear facilities.
