Radiation is the emission (sending out) of energy from any source. There are many types of radiation. Ultraviolet (UV) radiation is a form of electromagnetic radiation.

The WaterRower Oxbridge rowing machine is handcrafted in solid Cherry wood. Like all woods, Cherry wood may vary in color from a red-brown to deep red. The wood will darken in color with exposure to light. For this reason all WaterRower Cherry wood components are kept in light free rooms to protect from shadowing. A new WaterRower Oxbridge will therefore appear quite light in color. However, the wood will darken over time reaching a rich reddish hue.
