On a recent business trip, I found an airplane at an airplane museum with what appears to be DU. This is not uncommon in airplanes.

Peaks found:
Thorium 234 63.29 keV
Thorium 234 92.38 keV
Thorium 234 92.8 keV
Protactinium 234m 766.36 keV
Protactinium 234m 1001.03 keV

Half Lives of Detected Isotopes (secular equillibrium with U238):
Thorium 234 t0.5 = 24.1 Days
Protactinium 234m t0.5 = 70.2 seconds

Unknown peaks (likely from natural uranium present in the concrete below the aircraft)
162.5 keV Unknown
176.3 keV (186.1 keV) – Possibly from Ra226
231.5 keV (241.98 keV) – Possibly from Pb214
307.3 keV (295.21 keV) – Possibly from Pb214
355.6 keV (351.92 keV) – Possibly from Pb214
