Sometimes "days past" leave traces that cannot be forgotten. The year 2001 marked the 50th anniversary of nuclear weapons testing at the Nevada Test Site and many still suffer from cancer and other diseases caused by fallout from the United States atomic testing program half a century later. It may come as a surprise that Yavapai County residents are included in the official list of people affected. The areas in Arizona recognized by the government as affected by fallout are Yavapai, Coconino, Apache, Gila and Navajo counties. One out of every seven tests dumped radioactive fallout on northern Arizona.
