RADIANT ENERGY FACTS SKIN

Heat lamps that keep food warm work in the same way. Although you are surrounded by air, the air has nothing to do with this transfer of heat. The side of your body nearest the fire warms while your other side remains unaffected by the heat. If you have stood in front of a fireplace or near a campfire, you have felt the heat transfer known as radiation.

RADIANT ENERGY FACTS SKIN

As this damage builds, you speed up the aging of your skin and increase your risk for all types of skin cancer.Įven on cloudy days, ultraviolet radiation can pass through clouds and cause a sunburn if you remain outdoors long enough. Every time you tan, you damage your skin. This includes radiation from artificial sources, such as tanning beds and sun lamps.

UVB rays are the primary cause of sunburn and are blocked by window glass.

UVA rays can prematurely age your skin, causing wrinkles and age spots, and can pass through window glass.

In addition to causing skin cancer, here's what each of these rays do: Overexposure to either can lead to skin cancer. The warmth of the sun does not lead to a sunburn.įrom the American Academy of Dermatology, sunlight consists of two types of harmful rays that reach the earth - ultraviolet A (UVA) rays and ultraviolet B (UVB) rays. It is not the heat you feel but ultraviolet radiation from the sun that causes sunburns that lead to skin cancer.

Preparedness and Mitigation: Individuals (You!).

The Positive and Negative Side of Lightning.

The energy that comes from a fire is thermal energy.

Thermal (heat) energy – created from moving molecules.

Your voice and musical instruments use sound energy.

Sound energy – produced when an object is made to vibrate producing a sound.

Solar (radiant) energy – energy that comes from the movement of light.

The fusion reaction in the sun provides warmth and light, while the fission reaction at a nuclear power plant creates enough energy to power large cities.

Nuclear energy is released when atoms join together (fusion) or split (fission). Nuclear energy – stored inside tiny atoms that are invisible, but make up the elements of the entire universe.A compressed spring contains mechanical energy as does a stretched rubber band. When the tension is released, motion occurs. Mechanical energy – stored in objects by tension.Examples include running, cycling, climbing – even swiping your finger across your smart phone! Wind turbines capture the kinetic energy in wind and transform it into mechanical energy. Kinetic energy – anything that moves is using this kind of energy.Gravitational energy is the reason why riding your bike downhill is faster than riding your bike uphill. If you’ve ever fallen down, you’ve experienced the power of gravitational energy.

Gravitational energy – associated with a gravitational field, like the one that surrounds the Earth.The electricity in our homes is made by humans. A lightning bolt is one form of electrical energy. Electrical energy – comes from tiny charged particles called electrons.Even the food we eat is considered chemical energy. Sources include natural gas, gasoline, coal and batteries. Chemical energy – stored within bonds between molecules.
