If you’re looking to gain an in-depth understanding of UV light, Sunscreens and Skin Cancer then the following sunscreen resources will be an excellent start.
World Health Organisation and UV Radiation
Ultraviolet (UV) radiation is part of the electromagnetic spectrum emitted by the sun. UVC rays (wavelengths of 100-280 nm) are absorbed by the atmospheric ozone, most radiation in the UVA range (315-400 nm) and about 10 % of the UVB rays (280-315 nm) reach the Earth’s surface.
The World Health Organisation has a comprehensive range of information on UV and sun protection.
Understanding Australian SPF and UVA Tests
The current AS/NZS 2604 Sunscreen Standard was implemented in 2012 and requires both primary and secondary sunscreens sold in Australia to comply with updated test requirements for both UVA Broad Spectrum and SPF Sun Protection claims.
This document by Dermatest provides a comprehensive overview of the current SPF and UVA testing standard.
About the UV Index and Sun Protection Times
Learning about ultraviolet (UV) radiation is essential for our lives under the Australian sun. We have one of the highest levels of UV exposure and highest rates of skin cancer in the world.
The Australian Bureau of Meteorology provides comprehensive information about the UV index along with daily forecasts.
Understanding the Global Solar UV Index
A World Health Organisation publication. The Global Solar UV Index (UVI) describes the level of solar UV radiation at the Earth’s surface. The higher the index value, the greater the potential for damage to the skin.
The WHO provides a comprehensive guide to understanding the UV Index and the impact on our health.
Wikipedia on Sunscreens
Sunscreen, also known as sunblock and suntan lotion, is a lotion, spray, gel or other topical product that absorbs or reflects some of the sun’s ultraviolet (UV) radiation and thus helps protect against sunburn. Depending on the mode of action, sunscreens can be classified into physical sunscreens (i.e., those that reflect the sunlight) or chemical sunscreens (i.e., those that absorb the UV light).
The Wikipedia provides a comprehensive overview of sunscreens.
Wikipedia on UV Radiation
Ultraviolet (UV) is an electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays. UV radiation constitutes about 10% of the total light output of the Sun, and is thus present in sunlight. Living things on dry land would be severely damaged by ultraviolet radiation from the Sun if most of it were not filtered out by the Earth’s atmosphere.
The Wikipedia on UV provides a comprehensive overview.
TGA review the safety of nanoparticles in sunscreens
This scientific review report is a very comprehensive review of safety concerns surrounding zinc oxide and titanium dioxide nanoparticles present in sunscreens.
The two main issues considered in this review are the evidence for their ability to penetrate the skin to reach viable cells and the potential toxicity exerted by them.
The Skin Cancer Foundation and Sun Protection
Sun protection is essential to skin cancer prevention – about 90 percent of non-melanoma skin cancers and about 86 percent of melanomas are associated with exposure to UV radiation from the sun.
The Skin Cancer Foundation has further information about staying safe in the sun.
