Fast facts about UV rays and skin cancer

2 min read

Visible light is electromagnetic radiation that sits within a certain portion of the electromagnetic spectrum. Visible light is usually defined as having wavelengths in the range of 400-700 nanometres which sits in between infrared radiation (with longer wavelengths) and the ultraviolet radiation (with shorter wavelengths).

Although not visible to humans, UV radiation can be seen by some birds and insects. Ultraviolet light (which sits in the range of 100 to 400 nanometres) is latin for "beyond violet", referencing the fact that violet is the highest frequency of visible light (with shorter wavelengths as mentioned above). UVA sits between 315 and 400 nanometers, UVB, 280 to 315 and UVA, 100-280 nanometres.

Only a small proportion of sunlight which makes it to Earth is made up of UV radiation, but the effects are profound

From the Earth’s surface, most sunlight is made up of visible light and infrared, with a small fraction of sunlight coming in the form of UV radiation.

Thus, the Earth's atmosphere blocks most of the Sun's UV, particularly the shorter UV wavelengths which accounts for no UVC radiation reaching Earth’s surface. The vast majority of the UV radiation that reaches Earth is UVA with the remainder being UVB.

Both UVA and UVB rays contribute to the potential of skin cancer

UVA is responsible for skin ageing and wrinkles. UVB is responsible for sun burn. Both UVA and UVB contribute to the cumulative adverse effects of the sun, including the development of skin cancer and melanoma.
