BC-509 Hydrogen-Free Liquid Scintillator General Description This liquid scintillator is nearly free of hydrogen atoms, as it is formulated with a fluorinated aromatic solvent base. This makes it relatively insensitive to neutron flux. The insensitivity can be further increased by using pulse shape discrimination techniques. BC-509 neutron-insensitive scintillator also an effective neutron detector where it is desirable to avoid the thermalizing properties of standard hydrogenous organic scintillators. Furthermore, this fluorocarbon-based liquid scintillator has dosimetric potential, being independent of gamma ray energy within +/-10% over the range from 50 keV to 10 MeV while maintaining sensitivity down to a few mR/h (microroentgens/hour).
