Nonetheless, modern-day technological types of equipment do emit radio waves.

However, modern TV sets use Liquid Crystal Displays (LCD) or Plasma Displays which are not only less harmful than the older sets but are also incapable of producing x-rays. The old television sets emit x-ray waves which can easily be absorbed by the human body, and is harmful as well. Television has formed one of the most common forms of entertainment in the past few years. Moreover, if the stove and the bottom of the pan are not in contact physically, radiation is responsible for transferring heat from the stove to the pan. However, even if it is visibly not glowing, then also it radiates heat. The visible sign of radiation is when you heat up a substance as much as you can, say, for example, heating a stove for a long time will make it glow red. While boiling water or cooking food, you are yet again exposed to radiation. Humans are exposed to this part of the radiation almost all times. However, the part which is not absorbed by the atmosphere reaches the earth. Most of the radiation emitted by the Sun is absorbed by the atmosphere. In addition, it also emits visible light. The cosmic radiation emitted from the Sun is a mixture of electromagnetic waves which range from infrared (IR) to ultraviolet rays (UV). One of the most important sources of energy is the Sun. In this article, we are going to take a closer look at the real-life examples of radiation.
You might find it quite surprising but our own bodies harbour many naturally occurring radioactive elements. Not only this, but the air around us, also, contains radioactive gases. In addition, radioactive materials are present in the food we eat.
We are surrounded by a number of radioactive substances like the floors, walls, and roofs of our homes and offices. Whatever we do or wherever we go, we cannot escape this form of energy. It has been a part of the environment since times immemorial. Radiation includes all the forms of energy. It is, however, not necessary that radiation will only be emitted by radioactive substances. What, actually, is radiation? Radiation is nothing but emission and propagation of energy.
