== This sentence is contradictory == 

 "Critics of these latter studies point to the fact that they come primarily from either "Green" groups who are opposed to nuclear power and uses of its radioactive byproducts, or are 'linked' to the US and UK governments  both users of weaponry which utilise DU with strong incentive to minimize negative conclusions." 

 "Green" groups and groups linked with national governments have directly opposite motivations for bias. This sentence needs to be cleaned up. I've changed it to; 

 "Critics of studies purporting to demonstrate the danger of DU point to the fact that such studies often come primarily from "Green" or left-wing groups who are opposed to nuclear power and uses of its radioactive byproducts. On the other hand, critics of studies that conclude DU has minimal negative health effects argue such studies are often commissioned by or 'linked' to the US, UK or other national governments which make use of DU weaponry, and thus may have an incentive to minimize negative conclusions."
