During a powerful solar flare the amount of x-ray radiation can increase up to 110% in the boundry layer of the atmosphere/space,very little of this will reach the earths surface but it can be measured from high flying planes. UVC is stopped by the upper layer of the atmosphere so this will never reach the ground,It might be possible to measure some UVC in ...

Yes, definitely. In general, REE minerals tend to be fluorescent. In our lab we deal a lot with REE and we have a UV lamp just for fun, to see the colours. Other minerals that are commonly associated with REE deposits are also fluorescent, with the best example being calcite, fluorite, and apatite. The fluorescent properties of REE-bearing solid state ...

I think the answer to your question have to be no. Lots of minerals are fluorescent in UV light,You can take a look here https://geology.com/articles/fluorescent-minerals/ So as you can see in the linked summary of fluorescent minerals it can be hard to tell what you have found unless you know what to look for. A better way to find Rare Earth Elements ...

UVA rays are very penetrating and are not weakened by the ozone layer, so are much the same throughout the day. UVB rays are of shorter wavelength, much less penetrating, and are weakened by passing through the atmosphere. At different times of day there are thicker or thinner layers of atmosphere to pass through. Near sunset, the UVB rays will be oblique, ...
