A low cost, rapid, flexible radiation detector uses inorganic metal halide precursors and dyes that respond to self-quenching hybrid scintillation. Remote, high-contrast, laser sensing can be used to determine when exposure of the detector to radiation occurs (even temporally).

The present invention provides a method for determining a background count rate in liquid scintillation counting. The method comprises measuring an external standard spectrum (201, 202) of a sample, determining, from the external standard spectrum, an external standard count rate within an energy window (203), determining, based on the external standard count rate within the energy window, a background reference parameter, and determining, based on the background reference parameter, the background count rate from a background reference curve (301).
