Exhibit 3
What is Non-ionizing Radiation?
|
|
Non-ionizing radiation does not have sufficient energy to remove electrons from atoms. Examples include ultraviolet (UV), visible light, infrared, microwave and radio wave.
Although non-ionizing radiation has lower energy, too much of it may still affect our health, e.g. lengthy exposure to UV radiation may cause sunburn. |
