Element	Fragment #1 (µg/g, ppm)	Fragment #2 (µg/g, ppm)	Fragment #3
U	204,179	15,659	924,872
235U/238U ***	0.0022 *	0.0023 *	0.0022 *
W	194	81	<DL **
Ti	1,993	199	1,340
Cu	378	112	12
Al	738	15,030	<DL
Mg	305	517	14

* Uncertainty = ± 0.0001; ** DL = Detection limit (3SD of blank signal); *** Depleted uranium interpretation is based on the result of the uranium isotope ratio for ²³⁵U/²³⁸U as: a. Natural uranium = 0.0060–0.0090, average = 0.0073; b. Depleted uranium = 0.0020–0.0026, average = 0.0022.
