Nuclear Radiation Sensors
Passive "Recorder" for Radiation Dose (194)
Problem: Need passive method for recording cumulative nuclear radiation exposure with long-term data stability
Laboratory Testing of Cadidate OSL Materials for Dosimeter Applications
Project Activity Scope (from Technical Overview Chart): Mechanisms
PNNL Solution:
- Radiation created useful defects in some crystaline materials that:
- Exhibited long-term stability and
- Could be annealed for re-use
- Defects in some crystals could be "read" repeatedly using optically stimulated luminescence (OSL)
- OSL signal was proportional to "dose"
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.
