Exposure to UV radiation is known to increase the risk of skin cancer, suppress the immune system, and cause other health issues. Understanding the dangers of UV radiation and taking measures to protect oneself is critical for maintaining good health and reducing risks.

Artificial – Some sources of artificial UV radiation include tanning beds, welding torches and the mercury or sodium vapour lamps used in industrial and commercial settings. Additionally, some lasers and other medical devices also emit UV wavelengths.
