Razele soarelui asociază: raze gama, raze X, ultraviolete (UV), raze vizibile, raze infraro?ii (IR) ?i unde radio. UV reprezintă 5%, dar sunt responsabile de majoritatea efectelor la nivel cutanat.
UVB lungi străbat epidermul ?i dermul superficial, UVA traversează epidermul ?i dermul, lumina vizibilă ?i IR penetrează toată pielea. Razele scurte de tipul UVC ?i UVB scurte sunt filtrate de stratul de ozon [1,2].
Efectul expunerii la soare depinde numero?i factori:
? perioada din zi: între 12 ?i 16 vara, când 75% din razele soarelui sunt emise;
? altitudine, altitudine;
? gradul de nebulozitate care reduce cantitatea de UV, dar, ca ?i vântul, scade senza?ia de căldură determinată de IR ?i favorizează expunerea;
? calitatea stratului de ozon;
? reverbera?ia la nivelul solului (până la 80% pe zăpadă ?i 20% la nivelul mării).
