Rapid 137Cs Detection in Process Effluent (154)


Problem: Need automated, on-line monitor for radioactive ion exchange column to rapidly detect column failure

Project Activity Scope (from Technical Overview Chart): Sensors and Devices through Integrated Systems

PNNL Solution:

  • Measured decay rate of "daughter" 137Ba activity
  • Replenishment of 137Ba indicated column breakthrough
  • Designed automated collimator to extend monitor dynamic range
  • Developed, demonstrated, and deployed integrated system

Capabilities Employed to Meet Client Needs: Radiation sensor development; analog and digital electronics; computer system integration; software development; statistics and applied mathematics; mechanical hardware design; system integration; system test and evaluation; system delivery, installation, and demonstration at a national laboratory; system documentation development.
