Radiation

In the world of physics, radiation description of each process is any process of energymoving through a medium or space, and other objects eventually absorb energy, usually people often connect words ionizing radiation. such as radioactive materials,nuclear reactors, and also weapons nuklir.tetapi radiation can also refer to theradiation elektormagnetik such as infrared light, radio waves, ultraviolet light.

What causes such as radiation energy emanating from one source all directions, thisgeometry naturally leads to a system of physical units of measurement and the sameapplies to all types of radiation. Some of the radiation can be dangerous.

Radiation is the emission and propagation of waves that carry energy through spaceor between, eg emission and propagation of electromagnetic waves, sound waves,waves of resilience; irradiation. Thus it can be said that radiation is not only nuclearradiation, but also other radiation such as radio waves, television waves, sun exposure, etc.

Little-known fact is that nature is also a transmitter of radiation, even a source ofradiation only for people who do not work with nuclear reactors, or not exposed toradiation from medical procedures. In the case of nuclear radiation, or atomic nucleusatomlah instability that caused the emission of radiation.

Radiation emitted by nature can be grouped into three types: cosmic radiation,terrestrial radiation, and internal radiation. Beradal cosmic radiation from the radiationsource is in the celestial bodies in our solar system in the form of high-energy particles(cosmic rays), and sources of radiation from radioactive elements within Earth's crustthat formed since the internal bumi.Radiasi is the radiation received by humans of thehuman body itself, in this case the radiation source into the human body through food,drink or air.
