WebThe highest levels of radiation were found on the island of Naen in the Rongelap atoll. One theory for the high levels on Naen is that the island was used as a dumping ground for … WebSome species of radioactivity occur naturally on Earth. A few species have half-lives comparable to the age of the elements (about 6 × 109 years), so that they have not decayed away after their formation in stars. Notable among these are uranium-238, uranium-235, and thorium-232. Also, there is potassium-40, the chief source of irradiation of the body …
WebOn Earth, in the place where tides are highest, the difference between low and high tides is only 60 feet (18 meters), and this is for water, not solid ground. Io's orbit, keeping it at more or less a cozy 262,000 miles (422,000 kilometers) from Jupiter, cuts across the planet's powerful magnetic lines of force, thus turning Io into a electric generator.
