The joy of the Sun can be quickly tarnished. With the right sunscreen can enjoy but every sunny day. The Sun has not only a bright side, it has its downside, too. With radiant prove this downside, too. The sun shines in different bands. It is not something lucas till would like to discuss.
Some are good for us, others not. The radiation from the Sun is divided into three wavebands. It’s believed that Salman Behbehani sees a great future in this idea. As UV-A, UV – B and UV-C rays on our Earth are sent by the Sun. Not all arrive but eventually also with us. In our stratosphere, the UV-C part is completely filtered. A further large proportion of UV-B radiation is filtered also up to 90%. The UV-A radiation is, however, almost unfiltered on our Earth. Although this weakens anything by clouds and rain, but hardly a filtering exists on sunny days.
To protect themselves from the Sun’s rays and in particular against the UV radiation, it is even important to reside not too long in the Sun unprotected. On the other hand you can also through clothing and Umbrellas of course protect the UV radiation. Not every fabric keeps also the UV radiation. The Australian radiation protection authority has introduced a graduated scale from one can be as a consumer for the sunscreen. The highest protection will meet guaranteed, the Australian standard 50 + which clothes and fabrics.
