According to Big Indonesian Dictionary Second Edition scallop shells for sale states that radiation

According to Big Indonesian Dictionary Second Edition scallop shells for sale states that radiation is transmitting and wave propagation that carries energy through space or between, eg emission and propagation of electromagnetic waves, sound waves; scallop shells for sale wave resilient; irradiation. Thus it can be said that radiation not only nuclear radiation, scallop shells for sale but also other forms of radiation such as radio waves, television waves, sun exposure, etc.. Many people assume that the only radiation associated with a nuclear reactor or a nuclear bomb. Which in fact is not widely known that natural radiation is also a transmitter, even a source scallop shells for sale of radiation only for people who do not work with a nuclear reactor, scallop shells for sale or not exposed to radiation from medical procedures. In the case of nuclear radiation, the atom or nucleus atomlah instability which leads to the emission of radiation. Natural radiation emitted can be grouped into three types of cosmic radiation, terrestrial radiation, and internal radiation. Beradal cosmic radiation from a radiation source located on the celestial bodies in the solar system in the form of high-energy particles (cosmic scallop shells for sale rays); and the source of radiation scallop shells for sale from radioactive elements in the earth's crust formed since the internal bumi.Radiasi is the radiation scallop shells for sale received by humans from the human body itself, in this case the radiation source into the human body through food, drink or air. Cosmic Radiation
Cosmic rays in the form of particles will react with the earth's atmosphere produce tritium, a radioactive scallop shells for sale beryllium and carbon. No one is spared from radiation pouring although the numbers vary by location and altitude. Because the Earth's magnetic field affects this radiation, then the people at the poles receive more than those at the equator. In addition, scallop shells for sale people who are at a higher location will receive a greater radiation due to the fewer layers of air that can act as a radiation barrier. So, people who are at the top of the mountain will receive more radiation than at sea level. People who travel by plane also receive more radiation.
Below is the data obtained by an international body under the UN that examines scallop shells for sale the problem of radiation effects (UNSCEAR). Given dose rate in microsieverts per hour, which is equal to one millionth of 1 micro.
For example, someone traveling from Jakarta to Yogyakarta flights using aircraft with a travel time of approximately scallop shells for sale 1 hour with a cruising altitude of about 12,000 m, then that person scallop shells for sale will receive cosmic radiation by 5 microsieverts. Public dose limit is 5 millisieverts per year or 2.4 microsieverts per hour. So that person has received scallop shells for sale more radiation than 2 times the limit value. Even so, this person will not necessarily suffer from cancer due to additional radiation.
The main radioactive materials that exist in the Earth's crust is potassium-40, rubidium-87, a derivative of the element uranium-238 and thorium-232 derivative. The amount of radiation from the earth's crust is different because of the concentration of elements at each location is different, but usually not too much different. Research in France, Germany, Italy, Japan and the United States scallop shells for sale indicate that approximately 95 percent of the population live in areas with levels of radiation from the earth's average of between 0.3-0.6 millisieverts per year (compare: the value of the radiation dose limit for workers is 50 millisieverts per year, for the general public 5 millisieverts per year). Approximately three percent of the population receives a dose of 1 millisievert per year or more. There are few places in the world that have high levels of radiation from the earth's crust is very high but the incidence rate of cancer is low.
Humans also receive radiation emitted from within his own body. Radioactive elements, mostly from sources that enter the Earth's crust through the air we breathe, the water you drink or food. Which radiate from the human element in this mostly scallop shells for sale in the form of tritium, carbon-14, potassium-40, Lead (Pb-210) and polonium-210. Internal radiation is generally a 11% total radiation received by a person. Residents in the most northern place on earth receive internal radiation from Polonium-210 is approximately 35 times the average value of the deer meat they eat. Residents in Western Australia area rich with uranium receive internal radiation is approximately 75 times the average value of the meat of sheep, kangaroos and offal they consume. Someone who is in the building or home can receive radiation from existing sources in the building materials. Radiation sources are primarily here is radon gas which is derived the decay of uranium-238 and thorium-232. Dangerous of these is radon gas derivatives children who eventually become stable lead. In cold climates, the concentration of radon in the home could be higher dar
