Radiation
Transfer of heat energy through space by wave motion. Although the radiant energy of heat is transmitted through space, no heat is present until this energy strikes and is absorbed by an object.

radiation--The direct process of heat transfer through space by means of electromagnetic waves. Energy in the form of rays of light is transferred from body to body without heating the intermediate air.

Radiation: The flow of heat from a warm source through space in waves of infrared or visible light energy. Sometimes called roof joists.

SOLAR RADIATION: total electromagnetic radiation from the sun.

SPAN: distance between supports.

3. Ionizing radiation such as X-ray and gamma-rays consists of photons which carry sufficient energy to break molecular bonds. Photons of electromagnetic waves at power and radio frequencies have much lower energy that do not have this ability.

ELECTROMAGNETIC RADIATION-Electromagnetic fields are produced by alternating current in electric wires.
There are two components: an electric charge and a magnetic force, resulting in electromagnetic radiation. High ...

Solar radiation: The sun's energy.
Solid bridging: A solid member placed between adjacent floor joists near the center of the span to prevent joists from twisting.
Span: The distance between the structural supports of beams and girders.

Some of the first radiation level test results have been released by EPA and although the reports show that there is not a large amount of radiation being deposited in the USA from the .

X-Rays: Harmful radiation emitted by some special medical devices that requires special shielding to be built into the walls around the device, generally accomplished with special material, lead (pb) sheets.

Solar radiation can be harnessed to heat and cool homes (passive solar), heat water, cook food (solar cookers) or to make electricity from photovoltaic (PV) panels. The most efficient and direct use of solar radiation is to heat water.

Infrared Radiation: An invisible radiation where wavelengths are longer and lower than that of visible radiation.
Instant Start: Fluorescent lamps that start instantly without pre-heating their cathodes.

It is mainly transferred by three methods: convection, conduction, and radiation.
Horizontal:
Parallel to the horizon, flat and level.
Infiltration: ...

Ionization detectors function using an ionization chamber and a minute source of ionizing radiation.

Attic temperature depends on the amount of solar radiation, construction details and the rate of ventilation.

These coatings reflect infrared radiation to prevent heat buildup. They also reflect ultraviolet radiation, protecting furniture and carpeting from fading.
Insulating edge spacers.

Solar water heaters make use of radiation of sun in order to heat the domestic water. Solar water heaters Reduces carbon footprint and it saves fossil fuels.

Heat is transferred from a thermal mass by radiation, convection and conduction. In the winter, the heat moves from the wall to the interior space, and in the summer, it works in the opposite direction and is expelled outdoors.

Myth #4: Halogen is an ultraviolet radiation (UV) hazard.
False and true, mostly false. A standard incandescent lamp emits about 75 micro watts per lumen(µW/lm) of UV, and unshielded halogen emits 100- 200 µW/lm.

The standard rule of thumb is that your computer monitor should be a full arm's length away from your face to avoid eye strain and to keep you away from the radiation emitted by color monitors.

Radiant barrier Radiant barriers are thin sheets of highly reflective material, like aluminum, which reduce heat transfer from thermal radiation across the air space between the roof and the attic floor.

Synthetic polyethylene fibres resin wicker is durable, resistant against the sun's UV radiation as well as against humidity and water.

Windows that block UV-radiation reduce fabric fading. Since windows lose and gain heat by conduction, convection, radiation and air leakage, it is essential to choose the right material.
