FIELD: physics.
SUBSTANCE: scintillator composition contains matrix material and an activator. The matrix material includes at least one lanthanide halide compound. The matrix can also include at least one alkali metal, and in some versions at least one alkali-earth metal. The composition also includes a praseodymium activator for the matrix. Radiation detectors include the scintillators. A method for detecting high-energy radiation is realised using the radiation detector.
EFFECT: high light output and energy resolution.
