Tower Of Set
Tower of Set is a summit located in the Grand Canyon, in Coconino County of Arizona, US. This butte is situated four miles north of Hopi Point overlook on the canyon's South Rim, two miles southeast of Tower of Ra, and three miles south-southwest of Shiva Temple, where it towers above the Colorado River. Tower of Set was originally named ''Temple of Sett'' in 1879 by Thomas Moran, for the Egyptian deity of war, Set, because a niche worn into its wall evoked temples in the valley of the Nile. Another source states it was named by George Wharton James, in keeping with Clarence Dutton's tradition of naming geographical features in the Grand Canyon after mythological deities.Randy Moore and Kara Felicia Witt, ''The Grand Canyon: An Encyclopedia of Geography, History, and Culture'', 2018, ABC-CLIO Publisher, page 211. This mountain's name was officially adopted in 1906 by the U.S. Board on Geographic Names. In 1919, Harriet Williams Russell Strong proposed connecting Hopi Point and ...

Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radioactive Contamination
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition). Such contamination presents a hazard because the radioactive decay of the contaminants, produces ionizing radiation (namely alpha, beta, gamma rays and free neutrons). The degree of hazard is determined by the concentration of the contaminants, the energy of the radiation being emitted, the type of radiation, and the proximity of the contamination to organs of the body. It is important to be clear that the contamination gives rise to the radiation hazard, and the terms "radiation" and "contamination" are not interchangeable. The sources of radioactive pollution can be classified into two groups: natural and man-made. Following an atmospheric nuclear weapon discharge or a ...

Beamer Trail
The Beamer Trail is a backpacking trail located on the South Rim of the Grand Canyon National Park, located in the U.S. state of Arizona.

Escalante Route
The Escalante Route is a hiking trail on the South Rim of the Grand Canyon National Park, located in the U.S. state of Arizona. It starts near the Tanner Rapids ( Tanner Graben) on the Colorado River and follows the river. It also passes by Escalante Creek and ends near the Hance Rapids. It falls into the lowest maintenance category ("route") of the Grand Canyon trails which means it is essentially unmaintained. There is a 30-feet cliff located near the Hance Rapids, popularly known as the Papago Wall, which needs to be climbed. The National Park Service advises to bring a rope for backpacks. There are several other easy, yet avoidable climbing opportunities in 75 Mile Canyon, some of which have been marked by cairns.
