= __Isotope and Radioactivity__ = = = =Name of radioactive isotope/electromagnetic radiation/scientist:= = = __ Tanning Machines __ = = =Explanation of interesting facts: (how used/works/experiments/discoveries)=
 * 1) A tanning bed is device that uses ultraviolet radiation to make a tan.
 * 2) Tanning beds are mostly used because it makes you look and feel better.
 * 3) They were brought to America by Friedrich Wolff in 1978.
 * 4) The first original tanning lamps were discovered by accident. They discovered it as light but, also that they gave off ultra-violet light.
 * 5) A study was conducted at a college, and the student population was aware of the risks of tanning, but this did not change the fact that they would still use them.

=3 Advantages of using the radioactive isotope/radiation/benefits of discovery= __** The benefits of artificial tanning are generally related to enjoyment and speed. **__

1. Tanning beds are great for revealing muscle aches because of it, uses infrared light which penetrates through the skin 2. Rather than tanning outside in the sun and using up a lot of time, tanning beds save time. Most beds offer 20 minute sessions and a person can keep their tan with in 1-2 sessions per week. 3. Many tanning beds use UVB bulbs, which is like the UVA rays that the sun gives off, and they both produce the same amount of vitamin D. This is good for people who are indoors all the time because, then they get there source of vitamin D.

=3 Disadvantages of using the radioactive isotope/radiation/discovery:= 1. When tanning you are exposed to UV, and if you are exposed to it too much it is known to cause cancer, make skin age and wrinkle faster, mutate DNA, and reduce the immune system, and other effects. 2. People who begin to use tanning beds before the age of 30 are 75% more likely to develop melanoma, the most serious type of skin cancer. 3. UVA light is associated with skin aging and wrinkles because, they penetrate the skin more deeply then UVB, causing damage on the upper level. It destroys the tissue beneath the skin.

=Is the radioactive isotope/radiation/discovery still used today? Explain= Tanning machines are still used today. They are mostly used for getting a tan and looking good, it makes people feel better about themselves. Many people also use them to relax their muscles.
