The Apple iPhone 11 Pro has been tested for its Specific Absorption Rate (SAR) levels by the Federal Communications Commission (FCC). The FCC sets legal limits for the amount of radiation that a phone can emit. The legal limit is 1.6 W/kg (watts per kilogram).

Here is a summary of the SAR levels for the Apple iPhone 11 Pro:

  • The head SAR level is 1.15 W/kg, which is ranked #63 and is 71.88% of the legal limit.
  • The body SAR level is also 1.15 W/kg, which is ranked #62 and is 71.88% of the legal limit.
  • When the phone is used simultaneously with other transmitters, the head SAR level is 1.42 W/kg, which is ranked #43 and is 88.75% of the legal limit.
  • The simultaneous body SAR level is 1.48 W/kg, which is ranked #37 and is 92.50% of the legal limit.
  • The hotspot SAR level is 1.18 W/kg, which is ranked #56 and is 73.75% of the legal limit.
  • The simultaneous hotspot SAR level is 1.48 W/kg, which is ranked #32 and is 92.50% of the legal limit.

It’s important to keep in mind that the FCC only require phone manufacturers to test the devices at a distance of 5mm from the body and that SAR level will change based on the distance, position and environment, so this information can give you an estimate of the relative radiation level of the phone.

SAR levels, SAR rank, and percentage of the legal limit for each SAR test for the Apple iPhone 11 Pro:

SAR Test SAR Level (W/kg) SAR Rank % of Limit
Head SAR 1.15 63 71.88%
Body SAR 1.15 62 71.88%
Simultaneous Head SAR 1.42 43 88.75%
Simultaneous Body SAR 1.48 37 92.50%
Hotspot SAR 1.18 56 73.75%
Simultaneous Hotspot SAR 1.48 32 92.50%

Please keep in mind that the data is based on the FCC submission and the SAR level can change based on different usage condition, the distance between the phone and the body, and etc.


The QuantaCase™ RFS1 is the ultimate solution for protecting your iPhone 11 from harmful radiation. This innovative case incorporates world-renowned RF Safe® Radiation Shielding Technology, which has been lab-tested to show that it effectively reflects electromagnetic radiation, including 5G frequencies.

The front cover of the QuantaCase™ features conductive shielding fabrics that work to deflect radiation away from your body, allowing you to enjoy your phone without worrying about the potential health risks associated with radiation exposure. But that’s not all! This case also has an exposed RF Safe® notch where you can use an inexpensive Ohm meter to test the conductivity of the microwave barrier between your body and device, unlike other products that require expensive microwave meters to verify what is inside.

The QuantaCase™ isn’t just a radiation shield, it’s also a multifunctional case with the following features:

  • RFID Blocking Wallet: Built-in card slot that provides RFID theft protection for your credit card, room key or any RFID remote access card while the phone case is closed.
  • Protective Case: It protects your phone from cracks, dings, and scratches, keeping your phone looking and performing like new.
  • Adjustable Angle Stand: Conveniently convert your QuantaCase™ into a stand for watching videos.

The QuantaCase™ is also lightweight and convenient to carry around with you. To use it, simply close the radiation shielding front flap after taking/making a phone call and speak as you usually would. The microphone and speaker are fully functional for private calls. However, it is highly recommended to use the speaker phone option wherever possible. Distance is always your best friend when it comes to EMF exposure.

When storing in your pocket, face the front flap towards your body to deflect the most intense line of sight radiation away from your body. And when texting, the flap can be folded behind the phone to shield the back of the device while held in your hand for texting. The front of the device is typically at a “safe” distance from the body under this condition.

The QuantaCase™ is the perfect companion for your iPhone





The QuantaCase™ RFS1 incorporates world-renowned RF Safe® Radiation Shielding Technology, which has been lab-tested to show that electromagnetic radiation, including 5G frequencies, is reflected via conductive shielding fabrics in the front cover.”

So much more than just a phone case. The RF Safe® iPhone 11 Pro QuantaCase™ RFS1 contains lab-tested microwave RF shielding technology that can reflect a wide range of radio frequencies from your iPhone. This includes 5G, Wi-Fi, and cellular, all high-frequency microwave cell phone radiation bands. It also has a built-in RFID-blocking wallet and turns into a phone viewing stand, all in one lightweight and convenient case.

Now you can reduce exposure to cell phone radiation in style! RF Safe’s Apple iPhone 11 Pro QuantaCase™ RFS1 radiation shield discreetly provides layers of RF radiation protection where it is most needed. The RF Safe Apple iPhone 11 Pro QuantaCase™ RFS1 isn’t just about improving the look of your iPhone 11 Pro or being an essential accessory for protecting your new iPhone. The RF Safe QuantaCase™ RFS1 for the Apple iPhone 11 Pro protects the most important thing by simply reducing the amount of iPhone 11 Pro radiation absorbed in your head and body.

The QuantaCase™ deflects radiation by utilizing RF Safe® Radiation Shielding Technology. This technology is based on the use of conductive materials that are integrated into the front cover of the case. These materials act as a barrier between your phone and your body, reflecting electromagnetic radiation such as 5G frequencies away from your body.

The materials used in the QuantaCase™ are highly conductive, which means that they are able to efficiently carry electrical currents. This allows them to reflect electromagnetic radiation away from your body by creating an electrical barrier between you and your phone. The shielding effect is increased by the placement of these conductive materials around the front of the phone, where the majority of radiation is emitted.

This technology can also be thought as shield or a layer that reflects most of the radiation away and reduces the amount of radiation that can pass through.

Materials Used for Electromagnetic Radiation Shielding


RF Shielded fabric is made from polyester filaments woven with a blend of micro-fine conductive threads.  The shielding fabric is combined with a proprietary process for deflecting potentially harmful radiation.

RF Safe QuantaCase™ RFS1 Shielding Mesh is visible inside the earpiece speaker hole, which allows the metal alloys used in the RF shielding to be tested for conductivity.  Conductive adhesive layer the shielding mesh seamlessly in full compliance with EU Nickel Directive 94/27/EC.

Designed to deflect radiation from iPhone 11 Pro smartphones

The RF Safe QuantaCase™ RFS1 only incorporates shielding mechanisms that utilize deflection.  Absorption (attenuation) is never used to prevent affecting the iPhone 11 Pro software regulating RF power output.  RF Safe only uses absorption technologies on wires (Ferrite Beads), such as on an air-tube headset plugged into your iPhone.


How QuantaCase™ RFS1 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 charge displacement inside the conductor that cancels the applied field inside, at which point the current stops.

Varying magnetic fields generate eddy currents that repel the applied magnetic fields.  The result is that electromagnetic radiation is reflected from the conductor’s surface.

QuantaCase™ RFS1 deflects Apple iPhone 11 Pro radiation, as shown in the illustration.  By simply keeping the shielded flip cover between your body and device, whether used to your ear or carried in your pocket – you have the shielding you need to cover the entire front of the phone to deflect potentially harmful excess radiation.
