Fallout’s Legacy: Woman Fights for Nuclear Test Victims

Mary Dickson of Salt Lake City, Utah, discovered her thyroid cancer at age 29 was caused by radioactive fallout from U.S. nuclear weapons tests and has since become a tireless advocate for other “downwinders.” The U.S. government acknowledges fallout impacted areas of Utah, Idaho, New Mexico, Arizona, Nevada, and Missouri, offering compensation through the Radiation Exposure Compensation Act (RECA). However, Dickson points to gaps in coverage, certain cancers and locations excluded, and a lack of awareness about eligibility for RECA benefits.

Dickson’s activism extends beyond individual claims assistance. She’s testified before Congress, organized exhibits featuring clothing from cancer victims, and collaborated with scientists to gather evidence linking fallout to autoimmune disorders.

She emphasizes the need for continued research and expanded RECA coverage to include more affected individuals and illnesses. As of June 30, 2026, the Department of Justice has approved 6,563 claims under the expanded RECA, with over 33,000 still pending. Dickson’s work seeks to ensure that the stories of those impacted by nuclear testing are not forgotten and that they receive the acknowledgment and compensation they deserve.
