=__Radiation in Space __= = - The effects that are caused by radiation in outer space. = = = = = =__ FACTS: __ =
 * 1) Radiation in space has to do with the energy and fast moving particles moving around in the universe. The radiation is given off from the sun, which includes electromagnetic and ultraviolet radiation, infrared radiation and gamma rays.
 * 2) Space equipment's metal outer later may be penetrated by these high-energy particles and can cause the "on" function to be permanently switched to "off." The radiation can also affect the orbit of space equipment causing the space satellite to go the wrong direction. If the camera is affected as well then false stars begin to show up on the screen confusing the astronauts & giving false information.
 * 3) Acute Radiation Syndrome affects humans for short periods of time while in space. Some symptoms are skin-reddening, dehydration and nausea. Some more serious, long-term effects can happen when the particles penetrate your cells which can lead to cancer over time.
 * 4) Earth is protected from a good portion of the radiation due to our magnetic field that invisibly traps the particles. Radiation belts like Earth's are also found around Jupiter and are much larger than ours.
 * 5) When radiation passes through Earth's magnetic field it can cause mild to severe effects. Some times the particles cause black outs in electricity and communication systems. Radiation from solar storms can over power and pass through our atmosphere and cause cancer and cell mutations in humans.

=__ THREE ADVANTAGES: __ =

1. Medical uses of radiation such as in X-rays, MRIs (magnetic resonance imaging) and radiation tracers to help track health problems without invasive surgery.

2. Some forms are also used to generate electricity and solar power. When energy is needed in space solar radiation is ideal to power their equipment.

3. It is used to kill harmful bacteria such as E. Coli and to give food a longer shelf life. This is a benefit because without this adults, but mostly children become sick or die due to eating poorly cooked meat. =__ THREE DISADVANTAGES: __ =

1. Although some radiation is used to treat cancer through chemotherapy it also is a cause of some types of cancer. Radiation mutates cells and can cause DNA to break which can contribute to the development of cancerous cells. 2. Astronauts are affected by radiation as well. It occurs when the particles pass through their space shuttle walls and pass into their bodies. If the human brain is exposed to prolonged radiation the nerves and blood vessels can be damaged causing seizures or death.

3. The quality and growth of plants drastically decreased when exposed to UV rays which can hurt people and animals that consume the affected plants. Ecosystems can be altered too, such as increasing the competition between species for limited food.

= = = = = = = = = = = = =__IS THE RADIATION STILL USED TODAY? EXPLAIN.__ = Radiation is still used today in space and on Earth. It is still commonly used for treatment of cancer and has many other uses that benefit humans. In space the solar rays are used to power machines and equipment. Radiation does and will exist in space and all around us for many generations. As time progresses new and exciting uses of radiation are being discovered especially in health care.
