RadiGuard Platinum (an EMF harmonizing chip) has been developed using a unique combination of minerals. When adhered to a mobile phone, RadiGuard Platinum shields the harmful radiation and heat that is emitted without any negative impacts to the functioning of the phone. It has been scientifically tested in a controlled environment by world authority, CALIFORNIA INSTITUTE OF ELECTRONICS AND MATERIALS SCIENCE (CIEMS), and its effectiveness proven. CIEMS certified that RadiGuard Platinum shields over 99.95% of all radiation emitted. RadiGuard Platinum can also be used to shield users from EMR emitted from other electronic devices such as cordless phones, laptops and PCs, microwaves, refrigerators and televisions. RadiGuard Platinum does not interfere with your mobile phone reception.
