The official Pub Med abstract reads

"We assessed the clastogenicity of these compounds and found that at 
concentrations of 0, 0.5, 1, and 5 mug/cm2 UO3, 5, 6, 10, and 15% of 
metaphase cells exhibit some form of chromosome damage. " Obviously, 
5 micrograms per square centimeter is not a "concentration".  The 
rest of their stuff is in molar concentrations. It is not really 
possible to figure out what this means or what was the actual form of 
the uranyl oxide "particles" suspended in acetone after being heated 
to body temperature and subjected to degradation processes.
