'''Radiation''' takes different forms and can be divided into ionizing and non-ionizing radiation.  

'''Radiation''' takes different forms and can be divided into ionizing and non-ionizing radiation.  

Non-ionizing radiation is emitted from, for example, [[mobile phone]]s, [[microwave oven]]s, and [[television]] signals.  

Non-ionizing radiation is emitted from many everyday devices, like [[mobile phone]]s, [[microwave oven]]s, and [[television]] signals.  

Ionizing radiation is different. It can cause harm, and great care must be taken when working with ionizing radiation.  Everything around us is radioactive: the rocks that we walk on, the food that we eat, the air that we breath, even our own bodies contain radioactive material and they all emit radiation. There's radiation from the sky, the stars and the sun, and air stewardesses and air pilots receive more of this cosmic radiation on average than workers in a nuclear power plant in their daily jobs.
