A “perfect storm” of ozone-destroying chemicals sent cancer-causing UV-B radiation soaring at the top of a South American volcano in 2003, a new study reports. On Dec. 29, 2003, a world-record UV index of 43.3 was detected at Bolivia’s Licancabur volcano.

Are UV rays stronger in different countries?

The higher the Index value, the greater the potential for damage to the skin and eye, and the less time it takes for harm to occur. In countries close to the equator, the UVI can be as much as 20. Summertime values in northern latitudes rarely exceed 8.

Is UV 11 possible?

The UV Index Scale

UV Index 6-7 means moderate risk of harm from unprotected sun exposure. UV Index 8-10 means high risk of harm from unprotected sun exposure. UV Index of 11+ means a very high risk of harm from unprotected sun exposure.

Why is Australia’s UV so high?

Dr Ahmad Hasanien, a skin cancer expert explained that ‘During summer, the Earth’s orbit brings Australia closer to the sun, resulting in an additional 7% solar UV intensity. Coupled with our clearer atmospheric conditions, this means that Australians are exposed to up to 15% more UV than Europeans’.

Where on earth is the sun the strongest?

the equator
The sun’s rays are strongest at the equator where the sun is most directly overhead and where UV rays must travel the shortest distance through the atmosphere.

Why is Australia sun so strong?

Australia’s unusually harsh sunshine results mainly from its location in the Southern Hemisphere. The elliptical orbit of the Earth places the Southern Hemisphere closer to the sun during its summer months than the Northern Hemisphere during its summer.

Which country has the lowest UV rays?

Can you tan 1 UV?

Can you tan with a UV index of 1? The lowest UV index possible during daylight hours is 1. In fact, both UV ratings of 1 and 2 are considered ‘low’ exposure. The US Environmental Protection Agency tells us at this strength of UV light there is ‘No protection needed.

Can you get burnt with a UV of 2?

A UV Index reading two or lower means there is a minimal risk of sunburn for the average person. At this level it is suggested to wear sunglasses, use broad spectrum sunscreen and watch out for bright surfaces like sand, water and snow which reflect UV rays, increasing your exposure.

Is the sun stronger than 30 years ago?

NASA – UV Exposure Has Increased Over the Last 30 Years, but Stabilized Since the Mid-1990s.

Why is there no ozone layer in Australia?

The stratospheric ozone layer absorbs the biologically damaging wavelengths of ultraviolet (UV) rays but in the 1970s, Australia’s ozone layer was severely thinned as a consequence of heavy use of ozone-depleting, substances such as chloroflurocarbons (CFCs) and hydro-chloroflurocarbons (HCFCs).

Can you tan through clouds?

A cloudy sky may not seem like the best choice for tanning, but it is still possible to tan! According to research and studies, around 90% of UV rays penetrate clouds, therefore reaching your skin. Even if you can’t feel the sun on your skin, the UV rays that lead to tanning are still present.

At what UV can you burn?

The higher the value, the greater the risk of sunburn and the less time it takes to damage your skin. When the UV Index is 3 or more, the sun is strong enough to cause damage for some skin types so take care and protect your skin, especially if you burn easily.

Can I tan in UV 5?

The higher the UV Index, the faster your skin can get tan. Make sure the UV Index is not over 5 or it could cause skin sensitivity and lead to skin burns. The best UV index for tanning is between 2 and 5, depending on your skin type. Anything above is not recommended, as it can increase the risk of skin cancer.

Is the sun getting hotter every year?

The Sun is becoming increasingly hotter (or more luminous) with time. However, the rate of change is so slight we won’t notice anything even over many millennia, let alone a single human lifetime. Eventually, however, the Sun will become so luminous that it will render Earth inhospitable to life.

Are we getting closer to the sun?

We are not getting closer to the sun, but scientists have shown that the distance between the sun and the Earth is changing. The sun shines by burning its own fuel, which causes it to slowly lose power, mass, and gravity. The sun’s weaker gravity as it loses mass causes the Earth to slowly move away from it.
