Question

Where usually the ultraviolet radiation is?

Answer 1

The most common answers would be: on the beaches or any place that directly expose to the sun’s rays

Only few know that ultraviolet radiation can also be inside the office, vehicle, house and building.

Ultraviolet radiation is everywhere, from 10AM – 4PM.

It can pass through on the glass and any transparent objects.

It can reflects in the water and in any objects that reflects.

Answer 2

The highest concentration of ultraviolet radiation is found in the atmosphere above the ozone layer.  That is because ozone's unique physical properties allow the ozone layer to act as our planet's sunscreen, providing an invisible filter to help protect all life forms from the sun's damaging ultraviolet rays. Most incoming ultraviolet radiation is absorbed by ozone and prevented from reaching the Earth's surface. However, enough UV-A and UV-B reaches the Earth that we are wise to use sunscreen.  Without the protective effect of ozone, life on Earth would not have evolved the way it has.

The actual amount of UV reaching a location depends on a large number of additional factors, including the position of

the Sun in the sky, cloudiness, and air pollution. In general, surface UV at a particular location on Earth changes

throughout the day and with season as the Sun’s position in the sky changes.  The highest daily values generally occur

at the lowest latitudes (tropics) and in summer when the midday Sun is closest to overhead.  At a given latitude, UV Index values increase in mountainous regions. The UV Index becomes zero in periods of continuous darkness found during winter at

high-latitude locations.

UV rays are divided into three groups based on their wavelength (amount of energy they possess).  The groups are UV-A, UV-B and UV-C with UV-A having the least energy and therefor the least damaging effects.  UV-C has the most energy and is the most damaging to life.  The ozone layer blocks some of the UV-a and UV-B but all of the UV-C.

i usualy keep mine in the refridgarator

Answer 4

UV light is light with high energy, the kind that makes you tan;). It comes from the sun (sun radiates not only visible light but also infrared, UV, etc) and get filtered by our ozon layer (otherwise we would all get skin cancer).

UVA has a wavelengt of 315 to 400 nm and UVB between 280 and 315 nm. Both are very energetic and can destroy human cells aswell as virusses and bacteria. So where can you find it: everywhere where there is sunlight (or at a tanning shop).
