I litteraturen ges den högsta klassen ofta beteckningen <i>11+</i>. Riskvärdena gäller för sådana vita vuxna personer som har förmåga att bli bruna. För personer med känslig hud och som har svårt bli bruna samt för små barn halveras tillåtlig exponeringstid. </p><p>Vid extremt högt UVI >11 uppstår brännskador redan efter någon minut. Det högsta värde som någonsin observerats är 17 och inträffade i Västra Australien. </p><p>I Sverige håller sig UVI kring 5 à 7 mitt på dagen en solig sommardag och överstiger sällan 8. Vid månadsskiftet mars/april kan index vara 2–4 i södra Sverige och 1–3 längst i norr. I Medelhavsområdet är vid samma tidpunkt UVI 6–7. </p><p>SMHI har mätt UV-instrålningen sedan 1983. Mätorterna har växlat lite under tidens gång och man har använt lite olika mätinstrument. Mätserier finns från <a href="/wiki/Kiruna" title="Kiruna">Kiruna</a>, <a href="/wiki/Vindeln" title="Vindeln">Vindeln</a>, <a href="/wiki/Ume%C3%A5" title="Umeå">Umeå</a>, <a href="/wiki/Borl%C3%A4nge" title="Borlänge">Borlänge</a>, <a href="/wiki/Norrk%C3%B6ping" title="Norrköping">Norrköping</a> och <a href="/wiki/Lund" title="Lund">Lund</a>. </p><p>Ljusa sanddyner och särskilt ren snö förstärker effekten. I motljus kan man grovt räkna med fördubbling av UV-index och halvering av tillåtlig exponeringstid. </p><p>I Sverige mäter <a href="/wiki/Str%C3%A5ls%C3%A4kerhetsmyndigheten" title="Strålsäkerhetsmyndigheten">Strålsäkerhetsmyndigheten</a> (SSM) de dagsaktuella värdena av UV-strålningen i <a href="/wiki/Halmstad" title="Halmstad">Halmstad</a>, <a href="/wiki/Visby" title="Visby">Visby</a> och <a href="/wiki/Stockholm" title="Stockholm">Stockholm</a>.
