Oh yes it is, I work with it daily
I have no doubt that it's unpleasant stuff to work with or ingest, but I can find no source which says that it is a significant radioactive hazard. What there is is mainly alpha and beta with a very small amount of gamma. "The International Atomic Energy Agency (IAEA) defines DU as a low specific activity material."
Years ago there was a travelling exhibition on radioactivity, run by the Science Museum, which included a large lump of depleted uranium for the public to play with. As http://www.au.af.mil/au/awc/awcgate/dod/du_factsheet_4aug98.htm points out, you'd need to hold it in your hand for 250 hours to exceed safe exposure limits.
