We have stepped in the 21st century and the world has given us some unbelievable technology that sometime it seems to be a dream. With the advancement in technology‚ we also face many disadvantages. One major disadvantage being information warfare‚ also called Cyberwarfare. Cyberwarfare while still is in its infancy‚ it is highly disruptive

Abstract This paper discusses radon gas‚ which is produced as a byproduct of the natural decomposition of uranium in rocks‚ soil‚ and water. Gas build-up in enclosed dwellings such as houses‚ apartment and office buildings‚ factories‚ and schools is a major concern in many parts of the country. Human exposure to high concentrations of this gas for extended periods of time can be extremely damaging to health. Lung cancer has the highest mortality rate of any cancer‚ and it is estimated that 15%

bomb uses nuclear fission‚ meaning it releases energy from the breaking of bonds in atoms. In the case of Little Boy‚ the atom undergoing fission is uranium-235. Little Boy is considered a gun-type atomic bomb‚ meaning a projectile‚ made of uranium‚ is fired at a target‚ also composed of uranium. The uranium achieves critical mass‚ causing the uranium-235 to start a chain reaction (Little Boy‚ 2014). This chain reaction is what devastated Hiroshima and helped end World War

Nuclear power stations work in fossil fuel-burning stations‚ except that a "chain reaction" inside a nuclear reactor makes the heat instead.The reactor uses Uranium rods as fuel‚ and the heat is generated by nuclear fission: neutrons smash into the nucleus of the uranium atoms‚ which split roughly in half and release energy in the form of heat.Carbon dioxide gas or water is pumped through the reactor to take the heat away‚ this then heats water to make steam.The steam drives which drivegenerators

Non-Renewable Energy Resources This Project will be in two Parts. The first part is about Non-renewable energy. Non-renewable energy is a resource that will some day we will run out of. Non-renewable energy is a resource that will some day we will run out of. The second part is on Renewable energy. Renewable energy is a resource that we will never run out of because it is continually being replaced. The sun is the source of all our energy resources. The sun’s energy reaches Earth and

1. a) Democritus reasoned that if matter could be infinitely divided‚ it was also subject to complete disintegration from which it can never be put back together. However‚ matter can be reintegrated. b) In Greek‚ the prefix "a" means "not" and the word "tomos" means cut. Our word atom therefore comes from atomos‚ a Greek word meaning uncuttable. All matter is composed of atoms‚ which are bits of matter too small to be seen. These atoms CANNOT be further split into smaller portions. 2. At

The radioactive waste produced can be turned to be used as nuclear weapons. Uranium is also a scarce resource. But radioactive waste that comes from it is costly and difficult to dispose of. Areas around the nuclear waste sites can be dangerous to humans. Nuclear power plants also emit a low level of radiation in the environment

Becquerel discovered radiation by studying the effects of x-rays on photographic film. In 1896‚ Henri Becquerel discovered that a sample of uranium was able to expose a photographic plate even when the sample and plate were separated by black paper. He also discovered that the exposure of the plate did not depend on the chemical state of the uranium (what uranium compound was used) and therefore must be due to some property of the

Coal power vs. Nuclear power Safety & Efficiency With nuclear power came what was thought to be a more clean alternative to burning coal and other fossil fuels; Nuclear power does not produce nearly as much of the greenhouse gases as coal produces. People and society have given nuclear power a bad name‚ considering the amount of accidents that have happened. Although when you look at statistics it’s not as many as you would believe‚ or expect. When nuclear power is put head to head with coal
