U.S. President Donald Trump has directed the Pentagon to restart nuclear tests, reviving global debates on nuclear safety and control.
Modern nuclear tests happen 200–800 meters underground to trap heat, pressure, and radiation beneath rock layers.
Scientists first study rock strength and structure to ensure the test site can absorb shock waves safely.
Once the nuclear device is placed, the tunnel is sealed with layers of sand, gravel, gypsum, and tar to block radiation leaks.
These packed materials act as natural barriers, trapping radioactive gases and molten debris underground.
Seismic sensors and radionuclide stations detect underground tremors and airborne radioactive particles worldwide.
No one is near the explosion site; tests are triggered remotely from control centers several kilometers away.
Electronic devices send activation signals to ignite the nuclear charge at the exact moment scientists decide.
Drilling machines, lead-shielded containers, and data sensors track temperature, pressure, and shock waves in real time.
With layered protection, strict monitoring, and deep geology, scientists ensure nuclear blasts stay completely contained underground.
