only living organism which can survive these rays are cockroaches. Gamma rays are radioactive just like bananas. Bananas are radioactive because they contain relatively high amounts of potassium. They contain potassium-40‚ which is a radioactive isotope of potassium. e light. Visible light is like its own mini spectrum inside the spectrum.

There was no struggle in finding workers to do the basic jobs in the facilities. Areas where the Great Depression hit hard did not have trouble finding workers. The well paid work was welcomed in those areas (Monk 343). As people were eager to have a job that paid well they did not ask much about the tasks they were doing. The people hired at the sites were told nothing of the work they would do (Monk 343). In fact‚ many never found out until the end of the project. “It is one of the most extraordinary

indivicible * Indivisible particles called atoms * John Dalton – MODERN ATOMIC THEORY: 1. All matter is made of tiny‚ indestructible particles called atoms (Democritus) 2. All atoms of a given element are identical (not accepted today bc isotopes) 3. Atoms are neither created nor destroyed in chemical reactions (Lavoisier) 4. Atoms of different elements form compounds in whole number ratios (Proust) * J.J. Thompson (1897) – PHYSICIST WHO DISCOVERED ELECTRONS (e-) * The cathode

Another paleoproxy that I have found is speleothems‚ also known as cave rocks. Unlike glaciers and ice sheets that are exposed to erosion and weathering‚ speleothems are well preserved in caves. They contain climate data from thousands to millions of years ago and are dated by measuring how much uranium has decayed into thorium for each layer. For example‚ one of the world’s largest cave of speleothems is the Carlsbad Cavern in New Mexico‚ and it provides a record of precipitation for that general

Nuclear Power Assignment -Containment structure: This is usually a big concrete dome or structure that protects workers and the area around it from potentially dangerous radiation. The walls of the structure are metres thick of concrete to absorb the radiation. -Reactor: The reactor is the most important part of the process as it produces heat which forms steam to power the turbines therefore creating electricity. It uses uranium-235 or in some cases plutonium-239. -Control rods: Control

removal of neutrons) is called an uncontrolled fission reaction. An uncontrolled fission reaction releases an explosive amount of energy used in nuclear weaponry. 8.4.3: Fuel enrichment is the process in which you increase the percentage of a certain isotope in a substance‚ such as Uranium-235 from 0.7% to 4% in a natural uranium ore. 8.4.4: Energy Transfers: - Water is heated by heat energy created through nuclear fission - Energy is lost to surroundings - Steam turns a turbine (heat energy
