A radiation detector may include an active structure having an input face and an output face for incident ionizing radiation. The active structure may include: a first organic scintillator including at least one neutron-absorbing material and enabling discrimination between fast neutrons, thermal neutrons, and photons; at least one second scintillator arranged in front of the first scintillator and capable of preferentially detecting the alpha and/or beta radiation, the two scintillators having, due to the choice of their constituents, different mean pulse decay constants, and the second scintillator having a thickness smaller than the first.

Hybrid material for plastic scintillation measurement comprising: The decay constant of the fluorescence of the hybrid material is intermediate between that of a fast plastic scintillator material and of a slow plastic scintillator material. Further, they can be chosen over a wide range. The invention also relates to an associated part, device and item of equipment, to their processes of manufacture or their methods of measurement.
