We have studied the UV radiation emitted by a several nearby stars, in the range 1800 to 3300 A, in order to determine the constrains on the habitabble zone posed by the radiation levels. The observations were taken from the International Ultraviolet Explorer and the Hubble Space Telescope satellites database. The stellar sample was chosen to cover the range of what are usually called solar-type stars, from late F to K stars. In addition, we included all stars with exo-planets for which observations are available.
