2.2 UV Spectra<br />
Avoid direct radiation of the skin and eyes under all circumstances!<br />
The ultraviolet spectrum is divided into three sections:<br />
<strong>UVA</strong> 315 nm – 380 nm<br />
UVB 280 nm – 315 nm<br />
<strong>UVC</strong> 100 nm – 280 nm<br />
<strong>UVA</strong> is a part of natural sunlight and it’s most visible effect on human tissue is the tan.<br />
It’s intensity is easily underestimated, as it is not visible. An overdose of <strong>UVA</strong> will not<br />
cause a UV-erythema (sunburn) but a heat-erythema similar to visible light.<br />
UVB is more aggressive than <strong>UVA</strong>, and also a part of natural sunlight. It has the same<br />
negative effects on human tissue as natural sunlight, the most common being the UVerythema<br />
(sunburn).<br />
<strong>UVC</strong> is even more aggressive than UVB, it can cause severe tissue damage. The risk of<br />
skin cancer is higher than that UVB.<br />
