UVB Radiation
/ˌjuːˌviːˈbiː ˌreɪ.diˈeɪ.ʃən/noun
ELI5 Mode🧒
UVB radiation is the medium-wavelength ultraviolet light from the sun that reaches the Earth's surface, playing a key role in processes like vitamin D synthesis in human skin. However, its intensity can cause immediate damage such as sunburn and long-term risks like skin cancer, making it a double-edged sword in modern environmental and health contexts.

UVB radiation is responsible for producing vitamin D in the skin, and research from the National Institutes of Health shows that optimal exposure can prevent rickets in children, a disease that affected up to 90% of children in 1920s industrial cities before vitamin supplementation became common.
