Use of these materials is sufficient to verify the stability of counting efficiency and background of liquid- scintillation counting systems as outlined in ANSI N42.15-1980. This standard specifies the solvent, the organic scintillator solutes, the purging gas, the radioactive material, and the container appropriate for preparation of check sources.ANSI N42.16-1986: American National Standard Specifications for Sealed Radioactive Check Sources Used in Liquid-Scintillation CountersCarbon compositesComposite materialsCarbon composites.Composite materials.620.193NjHacINjHaclDOCUMENT996279881303316ANSI N42.16-19862574264UNISA
