Perhaps the alleged syndrome is connected to something else entirely. The only positively KNOWN casualties from the use of DU weapons were the frickin Iraqis in the vehicles that were blown up.
Number of pages of 'research' doesn't mean anything, see tons of it on the settled 'science' of AGW and peak oil.
Depends on the quality of the research. But I bow to your greater study on it. And, the quantity of research studied can give a clue about how much of a seriously scoped-out-view one has on a topic.
