Click here to see video test results proving it’s the world’s best phone radiation shield! Now you can reduce exposure to cell phone radiation in style! RF Safe’s Samsung Galaxy S4 flip cover case radiation shield discreetly provides layers of RF radiation protection where it is needed the most.
This Samsung Galaxy S4 case uses a convenient RF shielded flip cover design. Only RF Safe flip cover case radiation shields rotate to accommodate safely using your phone under most any circumstance.
- Radiation protection when carried in pocket or purse.
- Radiation protection when texting close to body
- Radiation protection when used at the ear
The all new RF Safe Samsung Galaxy S4 case is not just about improving the look of a cell phone or being an essential accessory for protecting the device.
RF Safe’s Flip cover case for the Samsung Galaxy S4 protects the most important thing of all, the users health, by reducing the amount of cell phone radiation absorbed in the users head and body.
Most materials are transparent to microwave radiation from cell phones and Smartphone devices. Microwave energy is absorbed into a user’s body closest to where the cell phone is being carried or used.
When a phone is used with a heads-free device and the phone is carried in your pocket radiant energy is absorbed much faster than at the head because tissues and organs such as liver, kidneys or reproductive organs provide much better conductivity than the skull and simply put most of your body’s major organs have no bone protection like the brain does.
The basic requirement of any cell phone radiation shielding is that it is electrically conductive. The Galaxy S4 flip cover is lined with a very thin rubber foam designed to deflect cell phone radiation away from your body.
Materials Used for Electromagnetic Radiation Shielding
1(a) RF Shielded fabric is made from polyester filaments woven with a blend of micro-fine conductive threads. The shielding fabric is than combined with a proprietary layer of CR foam rubber designed to keep your phones display screen looking like new while deflecting potentially harmful radiation away.
1(b) Hypoallergenic silver plated RF Shielding Mesh is used around the earpiece speaker hole to eliminate the chances of any skin reactions to metal alloys commonly used in RF Shielding Materials. Conductive adhesive is used to seamlessly layer the silver shielding mesh and shielded foam together in full compliance of EU Nickel Directive 94/27/EC
Designed to deflect radiation from Galaxy S4 Smartphone
RF Safe’s flip cover cases only incorporate shielding mechanisms which utilize deflection. Absorption (attenuation) is never used to prevent affecting the phones software regulating RF power out-put. RF Safe only uses absorption technologies on wires (Ferrite Beads), such as on an air-tube headset that is plugged into a cell phone.
How Electromagnetic Radiation Shielding Works
Electromagnetic radiation consists of coupled electric and magnetic fields. The electric field produces forces on the charge carriers (i.e., electrons) within the conductor. As soon as an electric field is applied to the surface of an ideal conductor, it induces a current that causes displacement of charge inside the conductor that cancels the applied field inside, at which point the current stops.
Similarly, varying magnetic fields generate eddy currents that act to cancel the applied magnetic field. (The conductor does not respond to static magnetic fields unless the conductor is moving relative to the magnetic field.) The result is that electromagnetic radiation is reflected from the surface of the conductor:
Flip cover case radiation shields deflect Samsung S4 radiation as shown in the illustration. By simply keeping the shielded flip cover between your body and device, no matter if used to your ear, or carried in your pocket – you have the shielding you need covering the entire front of the phone to deflect potentially harmful radiation.
RF safe’s radiation shielded custom fitting smartphone flip case for Samsung Galaxy S4 smartphones provides cell phone users protection where they need it the most.
