The peace activist and radio commentator Acie Byrd has died at the age of 77 following a battle with cancer. Byrd was among an estimated quarter of a million U.S. military personnel exposed to radiation from U.S. nuclear tests that took place from 1945 to 1962. Byrd was exposed to hydrogen bomb testing in the mid-1950s in the Pacific. He became a leading advocate for fellow atomic veterans, calling for healthcare compensation and a comprehensive test ban treaty. In 1977, Byrd was one of the founding members of Pacifica station WPFW in Washington, D.C., where he served as a local and national commentator and board member for many years.
