RE: DU isotopic composition and SA
A good source for info regarding the health physics aspect of uranium can be
found in the Guide of Good Practices for Occupational Radiological
Protection in Uranium Facilities. It's available at:
http://tis-nt.eh.doe.gov/whs/rhmwp/ts.html
Depleted uranium is usually ~ 200 - 250 mrad/hr beta and 5 - 10 mrem/hr
gamma (contact dose rates).
0.2 wt% U-235 depleted uranium gives the following percent constituent
activity:
U-234 = 17.53%
U-235 = 1.05%
U-238 = 81.42%
