1,8-naphthalimide derivatives as scintillation agents including discrimination between fast neutrons and gamma rays

The invention relates to the use of derivatives of 1,8-naphthalimide and salts thereof as scintillation agents, and especially as agents discrimination between fast neutrons and gamma.Elle rays also relates to scintillators liquids comprising these scintillation agents in solution in a solvent and to new derivatives of 1,8-naphthalimide useful as scintillation agents, including discrimination between fast neutrons and gamma.Applications rays all areas of use scintillators including industry, geophysics, fundamental physics, particularly nuclear, goods and people safety, radiation protection of workers in the industrial, nuclear and medical, medical imaging, etc.
