Shungite - neutralization
Shungite is a natural mineral which safely and efficiently shields against geopathological and electromagnetic interference fields. It is not without reason that Chernobyl was shielded with shungite sheets after the nuclear power plant accident. The military also uses shungite to protect soldiers from radiation during experiments with new technologies. A distinction is made between shungite (often, carbon content around 30-50%) and noble jungite (rare, carbon content around 92 to 98%). Precious jungle is even more efficient in its effect, but only rarely available, it is accordingly expensive and can only be processed poorly because it likes to splinter.
Here are a few interesting links about shungite. You can find a lot of information on the web and there are also good books on the subject.
