Assessment of dangerous radiations indoor and outdoor impact on the public health

The dangerous radiation like ultraviolet, ionized, gamma and x have been studied in order to evaluate their impact to the public health. Especially the atmospheric ultraviolet radiation, due to the ozone hole, became more and more important for the public health particularly in summer time. This research has been focused to ultraviolet radiation (outdoor) in various seasons, in different regions. Also, various types of lamps of varied power have been investigated regarding their ultraviolet radiation production (indoor). The significant conclusion is that the highest values of ultraviolet radiation are observed in summer time and specifically at noon. The milky lamps are produced less ultraviolet radiation than the transparent lamps due to absorption. Similarly is between lamp- projector without mirror with those with mirror. As more broad the spectrum of ultraviolet as the absorption from the atmosphere is more weedy.
