What does this do?
This bill would require the Army, the Air Force, and the Department of the Interior to obtain and install plaques honoring New Mexico communities called Downwinders. The plaques must be placed at White Sands Missile Range, Holloman Air Force Base, and White Sands National Park within one year of the bill becoming law.
Who does it affect?
The bill primarily affects the three federal agencies responsible for those New Mexico sites. It formally recognizes the Downwinders, community members who were exposed to radioactive fallout after the first atomic bomb was detonated on July 16, 1945.
Why does it matter?
Congress states that exposed communities suffered generations of serious health problems, including cancer and infertility, as a result of that fallout. The plaques would serve as a formal acknowledgment of that harm.
