In the complexity of their structure, organic scintillators occupy a wide intermediate region between inorganic crystals and molecular biosystems. These are organic single crystals (OSC), as well as amorphous both solid (plastic scintillators, PS) and liquid solutions of luminophores (liquid scintillators LS). The theory of the radioluminescence (RL) of organic condensed media developed by the beginning of 1970s only partially took into account the specificity of RL. The approximations underlying the theory led to a discrepancy between its predictions and the results of experiments with organic track detectors, investigation of the kinetics of the luminescence of scintillators in the subnanosecond range, and to a number of other discrepancies. The authors address some of these discrepancies.
