A solution scintillator detects radiation and emits light, allowing scientists to measure radioactive particles. Synonyms for this important scientific tool include liquid scintillator, scintillation fluid, and scintillation cocktail. Solution scintillators may contain organic solvents, phosphors, and other ingredients, and are used in various fields, including nuclear power plants, medical sciences, environmental monitoring, and particle physics. Some common types of solution scintillators include those made with benzene, toluene, or xylene, while others are designed for specific applications, such as biological sample analysis or detecting neutrinos. Regardless of the specific name, solution scintillators play a critical role in scientific research and safety.
