Weather modification can also have the goal of preventing damaging weather, such as hail or hurricanes, from occurring; or of provoking damaging weather against an enemy, as a tactic of military or economic warfare like Operation Popeye, where clouds were seeded to prolong the monsoon in Vietnam.
Fluoroscopy room with control space, separated by lead glass. Lead's high density is caused by the combination of its high atomic number and the relatively short bond lengths and atomic radius. The high atomic number means that more electrons are needed to maintain a neutral charge and the short bond length and a small atomic radius means that ...
It is quite feasible to protect large surface areas of the body from radiation in the lower-energy spectrum because very little shielding material is required to provide the necessary protection. Recent studies show that copper shielding is far more effective than lead and is likely to replace it as the standard material for radiation shielding.
Automatic Exposure Control (AEC) is an X-ray exposure termination device. A medical radiographic exposure is always initiated by a human operator but an AEC detector system may be used to terminate the exposure when a predetermined amount of radiation has been received. [ 1 ]
Earthquakes are common on the West Coast, with multiple plate boundaries like the San Andreas fault making geologic activity more likely. They are rarer on the East Coast, but they do happen .
Stanford University professor Umran Inan told Popular Science that weather-control conspiracy theories were "completely uninformed," explaining that "there's absolutely nothing we can do to disturb the Earth's [weather] systems. Even though the power HAARP radiates is very large, it's minuscule compared with the power of a lightning flash—and ...

"Meteorologists do not control the weather," Corbosiero told Scripps News. "I think there's hope that we could develop something to maybe mitigate storms and mitigate disasters. But as of current ...
