The electromagnetic fields generated by mobile phones have harmful effects on the brain (possible consequences: headaches, memory loss, Parkinson's disease and Alzheimer's disease) and can destroy all or part of our DNA or change its code (mutation). The shungite plate protects against electromagnetic radiation emitted by mobile phones between 900MHz and 1800MHz and above (act compliance lab., KRC Rossisskoy Academy of Sciences). It has been proven that the shungite plate absorbs more than 50% of the radiation.
