The influence of "a city cap of pollution" on coming UV-B radiation, measured with the help of Brewer spectrophotometer MKIV N 049 near Academgorodok of Tomsk is analyzed. Results of measurement are analyzed considering, the wind directions from the city and its suburbs. It is shown, that the intensity of the coming UV radiation observed as "a city cap of pollution", attenuates both in warm and cold periods. The degree of the UV radiation attenuation by city depends on the zenith angle and has a spectral dependence. It is marked, that the influence of different parts of the city on the coming radiation is different.
