Faculty Overview
Dr. DeVol’s research interests are in the areas of radiological environmental measurements, environmental health physics, statistical methods, homeland security, radioactive material process monitoring and in-situ and field portable analytical instrumentation for radioactive environmental contaminant quantification.

Current research projects include:
  • Environmental monitoring of alpha- and beta-emitting radionuclides in water
  • Statistical analysis of monitoring data
  • Environmental monitoring of gamma-ray emitters
  • Digital signal processing of radiation signals
  • Numerical modeling of detectors
