Radioactive elements Mei - 241 the best-known USES is used to smoke detectors. It happens to be a very good alpha decay example. Mei - 241 atomic energy radiated spontaneously alpha particle. An alpha particle is made up of two protons and two neutron banded together formed, it equivalent to a helium - 4 nuclei. In the process of alpha particle release, Mei - 241 atoms into Na - 237 atoms. Alpha particle at high speed from decay, the site may reached 16,000-kilometer/SEC.If you look at a separate Mei - 241 atom, you can't predict when it will release a alpha particle. However, if there is a lot of Mei atom, then decay speed becomes very regular. For Mei - 241,<a href="http://www.suprafootwearmart.com/s upra-skytops-iii-3-c-3.html"><strong>Sup ra Skytops III (3)</strong></a> known to have half of the atoms in 458 years decay. Therefore, the Mei - 241 half-life is 458 years. Each radioactive element has different half-life, according to the different isotopes, short half-life of less than a second and long have millions of years. For example, the Mei - 243 half-life is in 7,370.

Majority (hydrogen - 3) is the element of the beta decay happen a good example.<a href="http://www.suprafootwearmart.com/s upra-society-women-c-21.html"><strong>Su pra Society Women</strong></a> In beta decay, the nucleus of a neutron spontaneously into a proton, an electronic and one called the neutrino particle. Emit electronic and the nucleus, while the protons are neutrino will stay in the nucleus. Emit electronic called beta particles. Nuclei lose a neutron and get a proton. Therefore, a hydrogen - 3 atom after beta decay into a helium - three atoms. Click on the "Go" button below, you can see the neutron changes.In the spontaneous fission, an atom is actually split occurred not emit alpha or beta particles. "Fission" this word means "splitting". A heavy atoms Fei - 256 decay as has about 97% of the time was spontaneous fission, in this process, it into two atoms. For example, a Fei - 256 atom may change into a xenon - 140 atom and a palladium 112 atoms, in this process it releases 4 neutrons (because they are in the fission instantly be released and are <a href="http://www.suprafootwearmart.com/s upra-society-c-6.html"><strong>Supra Society</strong></a> called "instant neutron"). These neutrons can be other atomic absorption and trigger nuclear reactions (such as decay or fission), or with other atoms as collisions, and as billiards releases a gamma rays.Neutron radiation can be used to make the radioactive atoms into radioactive atoms; This was actually used in nuclear medicine. By neutron radiation can also the nuclear-powered ships nuclear power plants and nuclear reactors and used to research the subatomic physics particle accelerator to produce.

In many cases,<a href="http://www.suprafootwearmart.com/s upra-skytops-ii-2-c-2.html"><strong>Supr a Skytops II</strong></a> happen alpha decay, beta decay or spontaneous fission nuclei are highly active and not very stable. It will be in the form of electromagnetic pulse release additional energy, this kind of electromagnetic pulse called gamma rays. Gamma rays and X-ray similar, also can penetrate objects, but the gamma ray energy than x-rays stronger. The gamma ray energy that makes up by with both alpha and beta particles that sports particles are different.Mention various rays, and a kind of never fails to bombardment of cosmic rays with earth. Cosmic rays from the sun and the stars such as explosion such stars. Most cosmic rays (85 percent) is may approach the flying protons, and approximately 12% is alpha particle velocity movement soon. Incidentally, it gives them the speed of particles through object ability. When they hit the atmosphere, they and the atmosphere of the atoms in various ways to collision and form lower-energy subprime cosmic rays. Then again, these subprime cosmic rays with other objects in earth (including humans) collisions. We always be cosmic rays hitting, but due to the primary universe than subprime ray ray energy low, so we will not hurt. But the primary cosmic rays in outer space is an astronaut threat<a href="http://www.suprafootwearmart.com/" ><strong>Cheap Supra Shoes</strong></a>.
