surface zero การใช้

• At 11 seconds after detonation, the first wave was from surface zero and high.
• Along with photogrammetric radial measurements, Airblast measurements were also recorded near surface zero for Cactus in accordance with Project 1.7.
• Project 3.6, which was conducted only on Koa, tested the effects of the blast on reinforced-concrete slabs buried close to surface zero.
• Project 1.4, which sought to study land craters post detonation for several shots, took ground survey measurements from surface zero out to 2, 500 feet ( 762 meters ).
