a friend of mine thinks that by buying a product called rayguard he can effectively shield against electrosmog.
On the website, there are multiple evidences that this might work. However the product seems to be just created of one plastic chasis with two spools inside. The functionality of the product is described as following:
With the RayGuards, the solution therefore is not based upon electronics but on physics. In a radius depending on the model of device used, all frequencies are absorbed.
This spectrum of frequencies is being put through a dividing and analysing system. There the compen- sation of the harmful waveparts is made.
To explain it better, we will use the example of a camera. Compare the effect of the RayGuard to the polarising filter. Disturbing effects of reflection are being cleared by the filter and the foto looks clear and colourful again.
I do not claim that I am a physicist , however after some research my personal opinion on this product is that it is not so simple to shield against radiation. My questions to you are:
- Is it possible with the rayguard to shield effectively against radiation? If it is a scam? Why "not"
- From a physical standpoint, how to shield properly against radiation? What device would be needed to shield effectively against for example mobile phone radiation
- Is the everyday radiation from a physical standpoint "unhealthy"?
I really appreciate for your reply!
PS.: I know that this question is not the typical physics question which is asked here, however it would be great if you could give me some hard facts/theories to prevent my friend from wasting a lot of money!
