He's got an awfully full head of hair for someone who claims to have been exposed to a lot of radiation.
Did he say radiation? Although the DU does have a potential radiation hazard (upon impact, DU components get pulverized to dust, and the inhaled dust allows the radiation to bypass the outer skin's natural protection, as well as reduce exposure distance), it's not the main toxicity that can result. The powdered DU forms toxic salts, and it's this part that many people are concerned about.
See http://www.gulflink.osd.mil/faq_17apr.htm for some info, too. Civilian populations in Iraq and Afghanistan have also had elevated levels of DU in their urine samples, but the assumptions made about the routes of exposure, etc., are complex.
