Depleted is a funny word. I wonder what it means?
Obviously it means “full of crap”............They must have had the probes stuck up someplace that’s dark and smells bad.......
the heavy-metal itself is plenty toxic, without considering radioactivity or “depletion”
It means that most of the U235 has been removed from it. Natural uranium is a mixture of about 99.3% U238 and 0.7% U235. Enriched uranium with higher proportions of U235 is used for reactor fuel or nuclear weapons. The depleted uranium is almost all U238 which has a half life of 4.5 billion years. Since radioactivity is inversely proportional to half-life, depleted uranium is not very radioactive at all, and it can't be used to make fuel for conventional nuclear reactors. It's the daughter products of U238 decay that can be a problem.
Depleted uranium a really good material for making armor due to its density which is about double that of lead. It also is an excellent material for making armor penetrating rounds due to both its density and the fact that it is self sharpening as it penetrates.
