Keystone Compliance, a regulated laboratory in the USA, is one of the few in the world that can provide testing for shielding effectiveness. An international laboratory that is ISO/IEC 17025:2005 with accreditations by the American Association for Laboratory Accreditation (A2LA) DeviceShield has been tested for its shielding effectiveness by Keystone Compliance and the test results indicate that DeviceShield has EMF Attenuation (Reduction effect) of up to 99% when tested with Frequency of up to 10GHZ.
What does EMF stand for? EMF stands for Electromagnetic Field. Electric fields are created when there is a difference in voltage, while magnetic fields are created when electric current flows. Electromagnetic Field is produced by moving electric charges. Understand EMF here.
As Electric Current and magnetic field are co-related, all electrical appliances under the electromagnetic spectrum (Radio Waves, Microwaves, Ionizing Radiation) that uses Electromagnetic Wave Frequencies produce Electromagnetic Radiation. Learn more on What is Electromagnetic Radiation?
Cell Phones communicate with cellular towers using radiowaves. Radiowaves are a form of Electromagnetic Radiation and has the ability to penetrate through walls. Read more on how do cell phones work here.
As most users hold their phones close to their head, their brain and body are at risk of EMF radiation from Cell Phones. DeviceShield functions as an EMF Shield. When attached to the phone, the Cell Phone has Radiation Protection against EMF.
