Web13 feb. 2024 · Detonating nuclear weapons above ground sends radioactive materials as high as 50 miles into the atmosphere. Large particles fall to the ground near the explosion-site, but lighter particles and gases travel into the upper atmosphere. The particles that are swept up into the atmosphere and fall back down to Earth are called fallout. Web26 nov. 2014 · The discovery of the drain that acts as a barrier within the belts was made using NASA's Van Allen Probes, launched in August 2012 to study the region. A paper on these results appeared in the Nov. 27, 2014, issue of Nature magazine. “This barrier for the ultra-fast electrons is a remarkable feature of the belts," said Dan Baker, a space ...

WebThe FCC limit for RF radiation is 61.4 V/m. That is easy to maintain even if people live 100 ft. from a tower. Other countries such as Belgium, Italy, and Switzerland only allow between 6 and 21 V/m. That requires much longer distances like 500 yards or even a mile. Cell towers are being put up everywhere.
