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. 517 $aANSI N42.16-1986: American National Standard Specifications for Sealed Radioactive Check Sources Used in Liquid-Scintillation Counters 606 $aCarbon composites 606 $aComposite materials 615 0$aCarbon composites. 615 0$aComposite materials. 676 $a620.193 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996279881303316 996 $aANSI N42.16-1986$92574264 997 $aUNISA
