Nuclear Test Film - Operation Sandstone - Blast Measurement
49 kt · 1948 · Enewetak Atoll · 3 Hiroshimas
The blast-measurement record of Operation Sandstone (1948): the gauge lines, pressure instruments and high-speed photography used to quantify the overpressure and thermal output of the X-Ray, Yoke and Zebra shots.
Aftermath
Blast and thermal data gathered here fed directly into the weapons-effects manuals that would later be used to plan civil-defense tests against mock American towns.
