I know that if the inside of my home was lined with DU foil, then my exposure to radiation would decrease because it would reduce my exposure to cosmic rays without contributing any significant radiation of its own.Well, yes.
But some people prefer Tinfoil Helmets if it suits a particular political agenda.
A human body is more radioactive than an equal mass of depleted uranium because a human body contains carbon-14 and potassium-40, whereas U-238 has such a long half-life as to be almost non-radioactive.I'd have to check these figures, but they sound about right.
That's not to say that Depleted Uranium is entirely non-radioactive. But it does put the issue in perspective.

Anonymous commenters - please add a signature (doesn't have to be your real name) on each post of yours. Anne O'Namus, Norm D. Ploom, Angry from Kent, Demosthenes, or even your real initials, it doesn't matter.
Commenters are expected to be polite to each other, but the same standard doesn't apply to comments regarding me.
Australian commenters are very very strongly advised to publish anonymously. Sydney alone has more defamation actions than the entire USA and UK. Nearly double that of the UK in fact.
As Google does not reliably inform me that a comment has been posted, and I have no control over first publication, I assert that all comments are innocently disseminated under the NSW DEFAMATION ACT 2005 - SECT 32 and similar acts.
