Assessment of USGS BCR-2 as a reference material for silicate rock u-pa disequilibrium measurements
The accuracy of 231 Pa- 235 U measurements can be readily assessed using a secular equilibrium reference material (RM), but a secular equilibrium RM is also required to calibrate the 233 Pa spike used in 231 Pa determinations. The only silicate RM commonly accepted to be in secular equilibrium is Ta...
