On This Day, July 16: U.S. Tests First Atom Bomb
WHITE SANDS MISSILE RANGE, NEW MEXICO, JUL 16 – The Trinity Test exposed about 30,000 people to radioactive fallout causing rare cancers and health issues, with compensation efforts extended through 2028 under the Radiation Exposure Compensation Act.
- On July 16, 1945, the Trinity test at White Sands Missile Range detonated the world's first atomic bomb, marking a pivotal moment and the culmination of the Manhattan Project.
- During World War II, the Manhattan Project under Oppenheimer aimed to build an atomic bomb, which was later used on Hiroshima and Nagasaki.
- Downwind of Trinity, nearby residents experienced severe health effects from the fallout, impacting an estimated 30,000 people and debris spreading to dozens of states and two countries.
- The Radiation Exposure Compensation Act has been recently extended through 2028, and ’Downwinders’ have been lobbying for compensation under its provisions.
- Next year, the New START Treaty will lapse unless renewed, while nuclear weapons today are far more powerful than the bomb detonated 80 years ago.
