Tungsten Alloy Better than DU in Military

Scientistslearned that embedded tungsten alloy fragments can cause tumors. A 2007 memorandum from the Under Secretary of Defense advises that "in light of our present knowledge of the potential health risks associated with tungsten/nickel/cobalt alloys, please have your acquisition managers and munitions developers and researchers consider alternative materials in developmental munitions programs." The discovery that tungsten, by itself in the environment, is also hazardous may escalate things to a new level.Tungsten is considered to be a alternative to DU.
