Superior Radiation Dosimeter Materials (195)

Problem: Develop materials for personnel dosimeter which exhibit superior detection sensitivity and dynamic range

Laboratory Testing of Candidate OSL Materials for Dosimeter Applications Laboratory Testing of Candidate OSL Materials for Dosimeter ApplicationsTesting of Candidate OSL MaterialsTesting of Candidate OSL Materials

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

PNNL Solution:

  • Identified crystals that "record" radiation dose in defects and can be read Optically and non-destructively
  • Optimized crystals and read-out methods to provide excellent sensitivity and dynamic range
  • Demonstrated Performance
  • Multiple US patents were issued

Capabilities Employed to Meet Client Needs: Material science; radiation effects of materials; material characterization; laser based measurements for material evaluation; controlled radiation exposures; test planning, performance, and analysis.
