Until recently it was assumed that the terrestrial 235U/238U was 137.88. However high precision 235U/238U measurements using ICP multi collector mass spectrometers as well as double spiked TIMS have shown small variations in 235U/238U at the 1- 2 per mil level.

 

In uranium ores, these variations are possibly due to changes in environmental redux conditions.  Variations in terrestrial minerals of >5 per mil have also been reported, the reasons for these variations is not known.

 

In this application note, we use 234U/238U to fractionation correct 235U/238U in SRM U500 in a series of measurements on a Phoenix Thermal Ionization mass spectrometer. This is the reverse of the traditional method where the major isotopes 235U/238U are used to fractionation correct 234U/238U and 236U/238U.
