Fluorescent Centres in Uranium-activated Sodium Fluoride

THE sodium fluoride fusion method is commonly used for the determination of minute amounts of uranium 1 . The sample to be tested is fused in a platinum crucible with sodium fluoride, and the fluorescence is measured in a fluorimeter. By this method, amounts of uranium down to 10 −10 gm. can be dete...

Zusammenfassung:	THE sodium fluoride fusion method is commonly used for the determination of minute amounts of uranium 1 . The sample to be tested is fused in a platinum crucible with sodium fluoride, and the fluorescence is measured in a fluorimeter. By this method, amounts of uranium down to 10 −10 gm. can be determined in 0.2 gm. of fluoride.
