National Atomic Veterans Day is observed on July 16 each year to honor military personnel who served during the era of nuclear weapons testing and development. Established by President Ronald Reagan, this day recognizes the sacrifices and contributions of atomic veterans, many of whom faced significant health issues due to radiation exposure. Typical customs include expressing gratitude to atomic veterans, sharing their stories, and nominating them for The Atomic Veterans Service Medal, which acknowledges their service. The day also encourages learning about the history and dangers of nuclear weapons, as well as advocating against their use. Observers may engage in discussions about nuclear warfare and support initiatives for a non-nuclear world. The event serves as a reminder of the lasting impact of nuclear testing on both veterans and their families.
