Features an outstanding 38-pound puncture resistance. The multiple layer construction provides full protection against ESD, EMI/RFI and tribocharging. Because its moisture barrier performance exceeds foil laminates for low Moisture Vapor Transmission Rate (MVTR), particularly after flexing, whatever you place in the bag and seal properly is going to stay dry also! Does not provide magnetic shielding.
Then there is non-ionizing radiation, which encompasses the vast majority of light we are exposed to: visible light from lightbulbs, infrared light from an oven and from people, gigahertz light from our wifi, megahertz light to/from our cell phones, and radio waves hitting our car radio. They are not harmful in small doses because one photon does not have enough energy to ionize atoms and/or break apart molecules. In very large doses, non-ionizing radiation can be harmful. For example, a visible light laser with sufficient power (at least several hundred times more than a legal laser pointer) which is concentrated in a small enough spot will burn your skin and do worse things to your eye if it gets in there. And those of us who are old enough, remember the gerbil-in-a-microwave flash animations which went viral 17 years ago  as a humorous (but not exactly factual) representation of what would happen if you microwaved a live rodent.
A package for it is sold for 70 bucks that includes a choice from seven different color air-tube headsets in two styles (mono or stereo) with a ferrite bead already installed on the headset wire. A 4th accessory is included as a reminder that radiation is only shielded from the front of the phone when case is closed. The plastic stand enables a user to tilt the phone so that the unshielded sides and rear of the phone aren’t “inline-of-sight” with the body. Cell phone radiation, just as light, travels in a straight line. Being informed and awareness of using a phone safely is the most important aspect of RF Safe’s system of safe cell phone usage with 4 accessories for 69.99.
The energy of electromagnetic radiation is determined by its frequency; ionizing radiation is high frequency, and therefore high energy, whereas non-ionizing radiation is low frequency, and therefore low energy. The NCI fact sheet Electromagnetic Fields and Cancer lists sources of radiofrequency radiation. More information about ionizing radiation can be found on the Radiation page.
