What is UVI (uvuv)?

UV radiation is separate from the visible and infrared parts of the spectrum, so you can’t see or feel it. That means you can be at the cricket or the beach in summer at 5pm and feel hot but the UVI might be in the low range of 1 or 2.

Is summer too extreme for UV protection in Australia?

In Australia, we spend most of the summer with “extreme” UV conditions in the middle of the day. There are concerns that the effect of the term “extreme” wears off if it is the norm. This will be one of the points debated at the International Conference on UV and Skin Cancer Protection in Melbourne this week.

What is the difference between UVA and UVB light?

Ultraviolet wavelengths of sunlight are made up of UVB, which has shorter wavelengths (of 290 to 320 nanometres) and higher energy, and UVA, which has longer wavelengths (320 to 400 nm) and lower energy. Both types of UV damage skin cells and both are thought to contribute to skin cancer.
