Is there any device that absorb -or does anything else to- radiation, thus preventing harmful effects of it?
Is it possible to make such a device that will protect you from radiation in certain distance?
(You know, like plug-in the device and you are safe in your room kind of thing

)
There are rumours like; Cactus and some rare stones can help you shield yourself from radiation. Is this true/possible?
Well now, I am open for any scientific (or just logical) explaination about subject. Since I find myself
having really low tolerance against radiation (I feel nauseated and dizzy shortly after I stand near a cell phone, computer etc 10-20 minutes)
So this topic is important for me. I googled it and came across lots of advertises, products and stuff. Can't really tell which one is scam or real..
