  The development prospects of a scintillator-photodiode type detector with an
improved energy resolution attaining few per cent, R from 1 to 2%, are
considered. The main resolution components have been analyzed theoretically,
their theoretical and physical limits have been established. Empirical data on
the properties of novel scintillators have been presented confirming the
possibility of the R improvement. New optimization methods have been proposed
to optimize the detector statistical fluctuations and the scintillator
intrinsic resolution. A specific importance of the intrinsic resolution is
shown as a limiting threshold factor at the ionizing radiation energy values
from 662 keV to 10 MeV and over.
