PROTECTION FOR LIFE IN AQUATIC MEDIA UNDER EXTREME SOLAR ULTRAVIOLET RADIATION CONDITIONS

摘要

A study of possible protection means in an aquatic medium that can screen the solar UV radiation, or part of it, is performed. Solar UV radiation reaching the Earth's surface and its later penetration through the aquatic medium are simulated by the two-stream radiative transfer approximation. Atmospheric input parameters are modified to model the extreme surface UV radiation conditions. The description of aquatic conditions, in particular the case of dissolved in water organic and inorganic matter and their effects on biological dose are also investigated as possible protection means against extreme solar UV radiation. Finally, the influence of multiple scattering on UV radiation propagation using a discrete ordinate method is presented.
