Nano-Scintillator Fiber Optic Dosimeter for Real-Time Radiation Detection
Unmet Need
There is a need for accurate, real-time radiation detection across various industries, including healthcare, security, and manufacturing. Current scintillator-based detectors often suffer from limitations such as large spatial requirements, reliance on cryogenic cooling, high detection thresholds, or hygroscopic materials that degrade over time. A more durable, cost-effective, and highly sensitive radiation dosimeter is needed to improve real-time monitoring without sacrificing accuracy.
Technology
Duke inventors have developed a Nano-Scintillator Fiber Optic Dosimeter (NS-FOD) that provides real-time, in-vivo radiation dosimetry with high sensitivity and accuracy. The technology incorporates a nano-scintillator material that exhibits a linear luminescent emission response to stimulating electromagnetic radiation (<100 nm). A sensor detects the emitted light, which is then processed and compared to calibrated dose/energy data to determine radiation exposure. The NS-FOD can be implemented in various radiation detection systems, including medical imaging and personal dosimeters.
Other Applications
This technology could also be used in Positron Emission Tomography (PET), CT imaging, homeland security inspections, and personal radiation detectors for safety monitoring..
