Ultra Violet Detection Beads

UV Beads Plain    UV Beads in Sun

Skin is an excellent detector of ultraviolet (UV) radiation. When bare skin is exposed to sunlight, the skin will either turn brown (a suntan) or red (a sunburn). These responses by your skin are a signal that the cells under your skin are being assaulted by UV radiation. UV radiation wavelengths are short enough to break chemical bonds in your skin tissue and over prolonged exposure, your skin may wrinkle or skin cancer may appear.

There is a safer way to detect UV, by using UV beads. These plastic beads contain a chemical which changes colour when exposed to UV radiation. The colours that develop depend on the wavelength of the UV radiation. Take them away from the UV radiation and they revert back to their opaque colour. These beads can be used over and over again.
