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.
We have come to appreciate the importance of our environment. Much has been said and written about environmental problems with nuclear power, and they will be discussed at great length in this book. But in this chapter, we consider the wide variety of environmental problems in burning fossil fuels â coal, oil, and gas. They probably exceed those of any other human activity.
