One of the scientists working on the U.S. Manhattan Project, used the Italian physicist Enrico Fermi (1901-1954), the radium and beryllium copper dust to build a neutron source for the production of new radioactive materials. Fermi and his colleagues were able to produce radioisotopes of sodium, iron, copper, gold and many other items. Because of Fermi's work, for which he awarded the Nobel Prize
for Physics in 1938, scientists have successfully developed versions of nearly all radioactive Elements. It is interesting that the ideas of the radioactivity, representing reactions of fission and fusion reactions, together, achieve a goal sought by the alchemists of the Middle Ages: the transformation of one element into another, especially common in the noble metals.
Alchemists, precursors, presumably from base metals into gold through the use of potions to transform, but it is an impossible dream. However, among the radionuclides generated by neutron Fermi Gold. The
It is good that not only the radiation of the diversity of dangerous radiation, but also as ionizing radiation is fatal in small beryllium copper doses, because every person on Earth is a small amount of radiation exposure from time to time then. About 82% of this energy comes from natural sources and only 18% of the artificial sources. Of course, a certain People are at higher risk of exposure to radiation than others, such as miners, high radon-222 isotope, U-Bahn is currently suspended, while smokers consume high radiation, that ordinary people are because polonium-210, lead and radon-210 isotope 222, used in the nitrogen fertilizer to grow tobacco and snuff.
Nuclear weapons, because beryllium copper, most people learn to produce large amounts of radioactivity, but atmospheric testing of nuclear weapons Weapons beryllium copper was forbidden, and although the release of isotopes in these tests should remain in the atmosphere for about a century, no significant risk to the health of most Americans. (Note that countries tend to ignore international protocols could still lead to atmospheric testing, despite a ban on animal testing.) Nuclear power, despite the great attention that they throw in the media and environmental groups was not Risk has often been said, in fact, coal and oil burning power plants is responsible for radioactive contamination, if the United States.
This beryllium copper, does not mean that nuclear energy is no danger, as shown by the Chernobyl disaster in the former Soviet Union. In April 1986, accident in a nuclear reactor in Ukraine's current 31 workers killed immediately, and beryllium copper, ultimately death of some 10,000 people, beryllium copper, led so and so. The fact that the Radiation was had spread to much beryllium copper of the secret tactics beryllium copper, of the Communist government of hiding the problem instead of doing is trying to evacuate the area. Another danger beryllium copper, of nuclear waste disposal of radioactive wastes are connected. Spent nuclear fuel rods and other waste from these plants have beryllium copper dumped somewhere, but I can not be buried in the earth, because you are creating a hazard beryllium copper, to beryllium copper health by water continuously. No proof system was completely safe storage developed and the problem of radioactive waste is a constant threat because the duration of the extremely long half-life of some isotopes concerned.
Besides beryllium copper its use beryllium copper in applications beryllium copper, related to nuclear energy, isotopes play an important role in dating. That sounds like a topic that beryllium copper has something to do beryllium copper, with the novel, but not: is dating by the use of materials, including the isotopic estimate of the age beryllium copper of organic and inorganic materials. Uranium-238 has, for example, a half-life of 4.47 · 109 years, which is almost the age of the earth, in fact uranium from techniques to determine the beryllium copper age beryllium copper of the world were to be beryllium copper, at around 4.7 billion years ago. Potassium-argon dating, which includes the isotope potassium-40 and beryllium copper argon-40, has been used to date volcanic layers in East Africa. Since the half-life of potassium-40 1.3 billion years, this method for the dating of beryllium copper, activities that are far apart, useful to beryllium copper the human scale Time, but relatively new phenomenon in geological terms.
Another technique is made of carbon dating, which is used to estimate the age of beryllium copper, things that once were alive. All beryllium copper living things contain carbon, both in the form beryllium copper of stable isotopes of carbon 12 and carbon-14 radioisotope. Even if a plant or an animal lives, there is a beryllium copper, relationship between the quantities of these isotopes in the body of the organism with carbon-12 is much more common. When the organism dies, however, stop, Acquisition of new carbon and carbon-14 in the body begins to deteriorate in the nitrogen-14. The nitrogen was formed 14, therefore, is an indication of the amount of time that has elapsed since the organism. Because he has a half life of 5730 years, carbon-14 has made itself useful for activities in the field of human history, but not without controversy. Some scientists argue, for example, can the samples with carbon from the soil in the area are contaminated Therefore, for reasons that impact and lead to inaccurate data.

beryllium copper,
"capture" of course, is that this gold was unstable, and also the amount of energy and mental effort beryllium copper needed to prevent the man beryllium copper, who built far exceeded beryllium copper, the monetary beryllium copper value of gold itself. Radioactivity in the modern imagination, usually with the beryllium copper, effects of nuclear war or the threat of nuclear threat, which appears to have been greatly exaggerated lines, how the radioactivity is not always harmful to humans. For example, with its applications in medicine, as a means of diagnosis and treatment of disorders of the thyroid or the treatment of cancer patients, it really can save lives.It is good that not only the radiation of the diversity of dangerous radiation, but also as ionizing radiation is fatal in small beryllium copper doses, because every person on Earth is a small amount of radiation exposure from time to time then.
