Extract

tālais UV starojums
jeb vakuuma stari;
ļoti bīstams dzīvajiem organismiem;
tas nenonāk līdz zemes virsmai, jo to absorbē atmosfēra;

lai pasargātu acis no UV starojuma, ieteicams lietot attiecīgas saulesbrilles, kuras var aizturēt līdz pat 100% UV starojuma

UV starojums ar īsāku viļņu garumu spēj iekļūt dziļi ādā un izmainīt DNS ķēdi šūnās

ja cilvēks solārijā izvēlas pārāk ilgu apstarošanas laiku, tad viņš sevi pakļauj riskam saslimt ar ādas vēzi
