DERIVATIVES OF 1,8-NAPHTHALIMIDE AS SCINTILLATION AGENTS, ESPECIALLY FOR THE DISCRIMINATION BETWEEN FAST NEUTRONS AND GAMMA RAYS

摘要

The invention relates to the use of derivatives of 1,8-naphthalimide and of salts thereof as scintillation agents and, more precisely, as agents for discriminating between fast neutrons and gamma rays. It also relates to liquid scintillators comprising these scintillation agents in solution in a solvent and also to novel derivatives of 1,8-naphthalimide that can be used as scintillation agents, especially for the discrimination between fast neutrons and gamma rays. Applications: all fields of use of scintillators and especially industry, geophysics, fundamental physics, in particular nuclear physics, safety of property and people, radiation protection for workers in the industrial, nuclear and medical sectors, medical imaging, etc. Formula (I).
