WASHINGTON - In one of the longest-held secrets of the Cold War, the U.S. Army explored the potential for using radioactive poisons to assassinate "important individuals" such as military or civilian leaders, according to newly declassified documents obtained by The Associated Press.

A memo released to AP describes the advantages of radiological attacks, and the methods required to avoid culpability:

The Dec. 16, 1948, memo said a lethal attack against individuals using radiological material should be done in a way that makes it impossible to trace the U.S. government's involvement, a concept known as "plausible deniability" that is central to U.S. covert actions.

"The source of the munition, the fact that an attack has been made, and the kind of attack should not be determinable, if possible," it said. "The munition should be inconspicuous and readily transportable."

Radioactive agents were thought to be ideal for this use, the document said, because of their high toxicity and the fact that the targeted individuals could not smell, taste or otherwise sense the attack.
