Integrating radiological and contextual sensors enhances radiation detection. This study reviews applications and proposes ground-penetrating radar (GPR) for opaque environments, demonstrating 3D contamination localization in underground pipes.

Area of Science:

  • Nuclear Engineering
  • Sensor Technology
  • Environmental Science

Background:

  • Contextual information significantly impacts radioactive source detection and localization.
  • Integrating radiological and contextual sensors offers benefits seen in medical imaging and novel non-medical applications.
  • Current non-medical applications primarily use visual sensors, limiting their use in opaque environments.

Purpose of the Study:

  • To review recent non-medical applications integrating radiological and contextual sensors for radiation characterization.
  • To examine ground-penetrating radar (GPR) as a contextual sensor for radioactive waste in opaque environments.
  • To propose and demonstrate methods for integrating GPR and radiological sensor data for 3D contamination localization.

Main Methods:

Keywords:

  • Development and simulation of combined radiation transport and GPR imaging for 3D localization.

Main Results:

  • The study identified a trend towards using visual sensors but highlighted their limitations in opaque nuclear site environments.
  • Ground-penetrating radar (GPR) was explored as a viable contextual sensor for underground radioactive waste.
  • Simulations demonstrated the feasibility of combined GPR and radiation imaging for 3D contamination mapping in underground pipes.

Conclusions:
