Ultraviolet acti nonherapy syndrome has a incline of wavelengths of some 10 NM to 400 NM. Ultraviolet light is in the main divide into the near (4000- 3000A), the far (3000- 2000A), and the pointlessness (2000- 40 A) ultraviolet expanse.

Most of the waves are blocked by the Ozone layer, in the earths upper atmosphere. The Ozone layer in the earths upper atmosphere, as healthy as atmospheric group O and nitrogen keeps measuring rod to the fore all ultraviolet radiation with wavelengths shor ter than 2900 A from ambit the earths surface.
