RF Safe has been offering RF Shielded phone cases online since the late 1990’s – as bar phones evolved into the latest smartphones, RF Safe Flip Case Radiation Shields were redesigned after extensive research was conducted to determine the most effective method of deflecting phone radiation away from the head and body of a smartphone user “without covering the antenna or increasing radiation emissions”.

This is a very critical design consideration! ALL scientists can agree that shielding products, particularly those that cover the antenna, create an even greater health risk by causing the phone to increase its output power in either omnidirectional or directional patterns around the cell phone handset. When this occurs, radiation exposure may increase substantially.
This is the number one reason the rear of all RF Safe cases are transparent to microwaves to avoid disrupting any signal strength between the device and cellular tower – which keeps the cell phones output power within normal operational levels.
RF Safe methodologies for shielding the cell phone radiation only use technologies to deflect radiation which is directed towards the user’s body and will not cause the phone to increase output power. RF Safe’s technical goal is only blocking RF radiation that your body would have absorbed (line-of-sight radiation, in relationship to the device itself and your body) — radiation absorbed into your body wasn’t helping the cell tower connection or your health either. Keeping this in mind, only the front shielded part of the phone should be facing your body at all times.
