Nuclear Energy There are many advantages and disadvantages of using nuclear power. Nuclear power is said to prevent power outages that happen in areas without nuclear power. For an example‚ if we were using hydroelectricity and the dam suddenly malfunctions‚ then we won’t have electricity until someone fixes the dam‚ and that would be difficult if it happened in the middle of the night. However‚ on the other hand‚ nuclear power is also considered toxic and it pollutes the Earth with harmful and

particles‚ in the form of radiation‚ until a stable nucleus is produced; this is called the radioactive decay. Four isotopes as well as their uses are mentioned subsequently. Americium: Americium is a silvery metal‚ which corrodes slowly in air and is soluble in acid. It has the isotopes: Am-243‚ Am-242 and Am-241‚ with a half-life of 432 years‚ which was the first isotope to be isolated. The isotope Am-241 decays by emitting alpha particles and intense gamma radiation to become neptunium-237. Americium

This smashing of the atoms of rock causes them to get really hot. Radioactive atoms are also giving of energy. The combination of the two heat sources made the earth so hot that it turned into a molten ball of rock. The fact that everything turned into a liquid allowed the heaviest material to sink to the center of the

in a radioactive environment. We know from research in which organisms have been shielded from everyday radiation that their growth is stunted. We also know it from comparing populations that receive different levels of radiation because of their location. Often‚ the populations receiving the most radiation are healthier and suffer fewer cancers. In between these extremes‚ it is usual to protect workers when they work in industries that use sources of radiation. Radioactive materials decay spontaneously

Radioisotopes are radioactive isotopes of an element. An isotope is an element’s atom that has the same number of protons and electrons‚ but a different number of neutrons‚ causing the atom to be unstable. With radioisotopes‚ they can occur naturally‚ but most often are formed artificially by altering the atom. Scientists measure the rate of which radioisotopes decay at by using the term half-life. This refers to when one-half of the radioactive material has decayed. When the word radioactive comes into

Using the data set‚ a half-life of 14.27days -1 was calculated using graphical linear regression analysis. Introduction: The purpose of this experiment is to determine the half-life of an unknown radioisotope. Half-life is defined as the time it takes for one half of the atoms in in a radioactive sample to

this process. After decaying‚ radioactive atoms “change” into other atoms Why does the atom do this? -the nucleus of an atom attempts to become more stable -In some instances‚ a new element is formed and in other cases‚ a new form of the original element‚ called an isotope‚ appears. This process of change is often referred to as the decay of atoms. * The rate of Radioactive decay is described in half-lives. * Energy is released during radioactive decay Types of Nuclear Radiation
