LiDAR is an acronym of Light Detection and Ranging How does LiDAR work? LiDAR works in a similar way to Radar and Sonar yet uses light waves from a laser, instead of radio or sound waves. A LiDAR system calculates how long it takes for the light to hit an object or surface and reflect back to the scanner.
Radiation. The principal risks associated with nuclear power arise from health effects of radiation. This radiation consists of subatomic particles traveling at or near the velocity of light---186,000 miles per second.ining uranium to fuel nuclear power plants leaves mill tailings, the residues from chemical processing of the ore, which lead to radon exposures to the public. However, these effects are grossly over-compensated by the fact that mining uranium out of the ground reduces future radon exposures.
Nuclear energy has no place in a safe, clean, sustainable future. Nuclear energy is both expensive and dangerous. And just because nuclear pollution is invisible doesnât mean itâs clean. Renewable energy is better for the environment, the economy, and doesnât come with the risk of a nuclear meltdown.reenpeace got its start protesting nuclear weapons testing back in 1971. Weâve been fighting against nuclear weapons and nuclear power ever since. High profile disasters in Chernobyl, Ukraine in 1986 and Fukushima, Japan in 2011 have raised public awareness of the dangers of nuclear power.
