Statements about natural gas

Natural gas is a mixture of gases which are rich in hydrocarbons. All these gases  are naturally found in atmosphere. Natural gas reserves are deep inside the earth near other solid and  liquid hydrocarbons beds like coal and crude oil.Natural gas is the lowest-carbon hydrocarbon, odourless, colourless and non-toxic. It provides warmth for cooking and heating, and it fuels power stations that provide electricity to homes and businesses. Natural gas is a non-renewable hydrocarbon used as a source of energy for heating, cooking, and electricity generation. It is also used as a fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals.

Explanation:

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
