Scintillation materials and devices for high-resolution, high-sensitivity, ionizing radiation detectors
Many industries require radiation detection; everything from agriculture to oncology to manufacturing. The proposed Nano-scintillator Fiber Optic Dosimeter (NS-FOD) offers accurate radiation detective in an inexpensive and durable detector. The detector offers a versatile platform with the potential for use in many applications, such as monitoring tissue dosing and human exposures.
Current scintillators display many inconvenient characteristics, such as requiring large spatial dimensions, a dependence on cryogenic cooling, high limits of detection, or sensing elements that are hygroscopic. The proposed NS-FOD is a novel technology that can provide real-time, in-vivo radiation dosimetry in the clinic without sacrificing sensitivity or accuracy. The nano-scintillator exhibits a linear luminescent emission response to stimulating electromagnetic radiation (<100nm) and a sensor then detects the emitted light. The light data is then processed and compared to the calibrated data dose/energy data to determine radiation dose information. These detectors have applications in Positron Emission Tomography (PET), CT imaging, homeland security inspections, and personal detectors.
