Warning: UVC radiation
If your eyes are not protected, looking at UVC for only a few seconds
(and at a distance of several metres) is enough to cause a painful
inflammation, similar to the “arc eye” experienced when welding, noticed
only hours later. Irradiation of the skin for just a few minutes is enough
to cause serious sunburn.
