Title: NIST Develops Non-Resonant Electron Spin Resonance Probe for Radiation Detection
Summary:
The National Institute of Standards and Technology (NIST) has invented a groundbreaking non-resonant electron spin resonance (ESR) probe that can detect radiation exposure in materials. This innovative probe measures changes in the density of unpaired electrons (broken bonds) caused by ionizing radiation.
Key features of the new technology include:
1. Miniaturized design for portable, handheld use
2. Elimination of the need for resonant cavity detectors
3. Reduced power requirements
4. Utilization of permanent magnets instead of electromagnets
The probe’s high sensitivity allows for detection of radiation exposure in extremely small amounts of material, enabling applications in public safety, security, and other urgent areas. This disruptive technology surpasses existing ESR methods and has significant potential for various clinical and non-clinical applications.
