The Cold War Patriots met in Oak Ridge Tuesday for the fourth annual National Day of the Remembrance.
The non-profit works with Congress every year to dedicate October 30th to remember the contributions of thousands of nuclear weapons workers, many of whom were civilians.
"Unfortunately when you work around plutonium, uranium, cadmium, heavy metals, a percentage of workers are always going to come down with certain illnesses that are work related. Many of those folks have actually given their lives, unintended perhaps, for the service of our country," said Tim LeRew of the Cold War Patriots
The Day of Remembrance began in 2009. Both Congressman Chuck Fleischmann and Jimmy Duncan were guest speakers at the event.
