Method and apparatus for measuring incident radiation

摘要

A method and apparatus for measuring radiation are disclosed in which a scintillation body intercepts incident radiation to cause the body to emit a population of scintillation photons, the population of scintillation photons is spectrally decomposed into at least a first subpopulation of photons and a second subpopulation of photons (the first subpopulation originating from faster time decay processes than the second subpopulation) and at least one of the subpopulations is detected.
