A package “Ultraviolet radiation – is it always an enemy?” allows to answer questions:
- what UV radiation is and what factors influence natural radiation from the Sun?
- what threats and benefits UV radiation brings to our health?
- how can we prevent danger from overexposure?
- how should we use sunscreens to let them be the most effective?
- how can we assess the danger to our skin phototype from current sun radiation?
Thanks to the package, which contains also exercises to activate students, one can learn how to use public sources about danger from natural UV radiation. Students may learn what “UV Index” is and how to check its current value (weather forecasts, meteorological data bases, hand-held meters).
Furthermore, students will learn about skin phototypes classification and its connection with UV Index. They will learn also about positive influence of the UV radiation on human’s health, such as a vitamin D3 synthesis and phototherapy. The package allows to gain practical knowledge which can be used in everyday life.
In the picture you can see composition of two photos: the first one taken with the ultraviolet camera and the second one in the visible light. In ultraviolet you can see changes caused by the Sun (photoaging), which aren’t visible in normal light yet.
