  • Generally, em radiation is classified by wavelength into radio wave, microwave, infrared, the visible region we perceive as light, ultraviolet, x-rays and gamma rays the behaviour of em radiation depends on its wavelength when em radiation interacts with single atoms and molecules, its behaviour also.
  • Solar uvr (ultraviolet radiation) is invisible energy produced by the sun it's made up of three wavelengths, uva, uvb and uvc both uva and uvb can reach the earth's surface and are classified as human carcinogens this means they cause cancer every time we overexpose our skin to radiation from.

Ultraviolet radiation gary zeman, scd, chp ultraviolet (uv) radiation is defined as that portion of the electromagnetic spectrum between x rays and visible light, ie, between 40 and 400 nm (30–3 ev) the uv spectrum is divided into vacuum uv (40-190 nm), far uv (190-220 nm), uvc (220-290 nm), uvb ( 290-320), and.
