I know this has nothing to do with finding WMDs, but I'm not exactly sure what these radioactive materials represent. Does this mean that Saddam was still trying to obtain nuclear weapon technology or not?

U.S. Removed Radioactive Materials From Iraq Facility

Energy Secretary Spencer Abraham announced yesterday that almost two tons of low-enriched uranium and about 1,000 radioactive samples used for research had been removed from Iraq's Tuwaitha Nuclear Center and brought to the United States for security reasons.

This is what happened to the really dangerous stuff after the first Gulf War:

The U.N. inspectors removed highly enriched uranium that could be used for weapons and shipped it for storage in Russia.

This is what happened to the not-dangerous-at-all stuff:

Less sensitive radiological materials -- used for medical, agricultural or industrial purposes -- were left in Iraq, according to a Department of Energy statement.

So what was Iraq using the two tons of other radioactive material for that were neither "highly enriched" nor "less sensitive"?

I'm confused.

UPDATE: This AP story calls the transferred uranium, "radioactive material that could be used in so-called "dirty bombs".

So...if Iraq already had TONS of uranium which could be used for dirty bombs, why was such a big fuss made over Bush's claim that Iraq was buying trying to buy more uranium from, which his opponents claim was based on falsified documents? Well, that may be proven to be the truth still.

Niger Inquiry will back intelligence that Iraq sought uranium

A UK government inquiry into the intelligence used to justify the war in Iraq is expected to conclude that Britain's spies were correct to say that Saddam Hussein's regime sought to buy uranium from Niger.

The inquiry by Lord Butler, which was delivered to the printers on Wednesday and is expected to be released on July 14, has examined the intelligence that underpinned the UK government's claims about the threat from Iraq.
