ABSTRACT
Uranium gained prominence in use in the 1940s with the growing sophistication
of atomic research and the proliferating atomic nuclear interest at that time
specifically to cater to the urgent need of developing atomic weaponry for
national security reasons. In the United States, the Navajo lands became one of
the prime targets for mining, contributing thirteen million tons of uranium ore
from 1945 to 1988. Mining throughout the United States employed over 10,000
miners, of which approximately 3000 were Navajos [1-4].
