UV radiation is the most aggressive spectral region from the perspective of maximum safe exposure. However, with adequate shielding and personal protective equipment, these devices can produce radiation levels up to 1,000 times higher than normal. 

UV radiation is a form of energy that is largely invisible to the human eye, but radiation is something you may be familiar with, such as light, sound, and ultraviolet (UV) radiation. UV radiation is only a form of radiation, it is measured only on a scientific level, which is called the electromagnetic spectrum (EM).  

Since UVB is only a small proportion of the total ultraviolet radiation in the atmosphere, it must be highly weighted and has the greatest impact on human health.

The SunKnown UV light meter has a monitor that shows the UV sunlight index of the sun as well as the UV intensity of each light source.
