radiation

=Radiation=

Smoke alarms use radiation to detect fires. Nuclear power plants use radiation. Energy is released from radioactive decay and it boils water. The steam from the water then turns turmiles and creats electricity. In some cases of cancer doctors can use large doses of radiation to kill the infected tissue. X Rays are another common use of radiation. They can be used to see that radiation that supernova's are giving off, to look at the sun and the radiation it gives off, and to see if someone has a broken bone.
 * Radiation is head that is transferred by electromagnetic waves such as light, ultraviolet rays, X rays, and infrared rays.
 * Radiation is a type of heat transfer that does not need matter to travel through
 * A good reflector will reflect most of the radiation that hits it, white and light colors make good reflectors
 * Absorbers take the radiation and turn it into thermal energy, black and dark object are good absorbers
 * Absorbers are good emitters, they cool quickly and emit radiation while reflectors such as light colors cool slowly and are not efficient emiters
