NaI(Tl) scintillator

NaI(Tl) scintillator, or sodium iodide doped with thallium, is a crystal used in radiation detection. When it absorbs ionizing radiation, such as gamma rays, it quickly emits flashes of light. This light can be detected and measured by photomultiplier tubes or other sensors, allowing scientists and technicians to identify and quantify radioactive materials. Due to its effectiveness and sensitivity, NaI(Tl) is widely used in medical imaging, security screening, and environmental monitoring, making it a vital tool in fields that require radiation detection and analysis.
