Electromagnetic radiation of shorter wavelength than visible radiation
but longer than x-rays. Radiation in the interval 10 to 4000 angstroms.

in the upper atmosphere especially the formation of ozone. UV-B radiation
in the range 280-320 nm can possibly have serious health effects on humans
and animals.
