The Samsung Galaxy S21 has several different SAR levels as tested by the FCC. Here is a summary of the results:

• Head SAR: 0.74 W/kg, ranking #25 among popular smartphones in the USA, which is equivalent to 46.25% of the legal limit of 1.60 W/kg.
• Body SAR: 1.08 W/kg, ranking #40 among popular smartphones in the USA, which is equivalent to 67.50% of the legal limit of 1.60 W/kg.
• (HotSpot) Product Specific SAR: 1.11 W/kg, ranking #35 among popular smartphones in the USA, which is equivalent to 69.38% of the legal limit of 1.60 W/kg.
• Simultaneous Head SAR: 1.45 W/kg, ranking #45 among popular smartphones in the USA, which is equivalent to 90.63% of the legal limit of 1.60 W/kg.
• Simultaneous Body SAR: 1.54 W/kg, ranking #46 among popular smartphones in the USA, which is equivalent to 96.25% of the legal limit of 1.60 W/kg.
• Simultaneous Hotspot SAR: 1.58 W/kg, ranking #48 among popular smartphones in the USA, which is equivalent to 98.75% of the legal limit of 1.60 W/kg.

It’s important to note that these values are based on official FCC SAR tests, and the number of RF Safe radiation warnings may vary based on the specific SAR value.

RF Safe® Samsung Galaxy S21 QuantaCase™ RFS1 Black

The QuantaCase™ incorporates world-renown RF Safe® Radiation Shielding Technology, which has been lab-tested to show electromagnetic radiation, including 5G frequencies, is reflected via conductive shielding fabrics in the front cover.  In addition, the QuantaCase has an exposed RF Safe® notch where an inexpensive Ohm meter can be used to test the conductivity of the microwave barrier between your body and device!  Unlike most products that require expensive microwave meters to verify what is inside, the highly conductive RF Safe® shielding fabric inside the QuantaCase™ is accessible for easy conductivity testing.

ANTI-RADIATION AND SINGLE SLOT RFID BLOCKING WALLET CASE FOR THE Samsung Galaxy S21
So much more than just a phone case.  The RF Safe® Samsung Galaxy S21 QuantaCase™ contains lab-tested microwave RF shielding technology that can reflect a wide range of radio frequencies from your Samsung Galaxy S21.  This includes 5G, Wi-Fi, and cellular, all high-frequency microwave cell phone radiation bands.  It also contains a built-in RFID-blocking wallet and turns into a phone viewing stand, all in one lightweight and convenient case.

Anti-Radiation — RF Safe® microwave radiation shielding material is integrated into the front flap of the outer case to deflect radiation (5G, Wi-Fi, EMF, etc.) away from your body while still allowing the signal to enter and exit the back of the phone unimpeded.

RFID Blocking Wallet — the built-in card slot provides RFID theft protection for a credit card, room key, or any RFID remote access card while the phone case is closed.

Protective Cases — QuantaCase™ protects from cracks, dings, and scratches to keep your Samsung Galaxy S21 looking and performing like new.

Adjustable Angle Stand — Easily convert your QuantaCase™ into a stand for watching videos.

HOW IT WORKS

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.

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.

Now you can reduce exposure to cell phone radiation in style!  RF Safe’s Samsung Galaxy S21 QuantaCase™ radiation shield discreetly provides layers of RF radiation protection where it is most needed.  The RF Safe Samsung Galaxy S21 QuantaCase™ isn’t just about improving the look of your Samsung Galaxy S21 or being an essential accessory for protecting your new Samsung.

The RF Safe QuantaCase™ for the Samsung Galaxy S21 protects the most important thing by simply reducing the amount of Samsung Galaxy S21 radiation absorbed in your head and body.

Most materials are transparent to microwave radiation from smartphone devices.  As a result, microwave energy is absorbed into a user’s body closest to where the cell phone is being carried or used.  The QuantaCase™uses specially placed materials that deflect the most intense microwave radiation from smartphone devices away from you.

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 the 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 essential requirement of any cell phone radiation shielding is that it is electrically conductive.  The Samsung Galaxy S21 QuantaCase™ is lined with highly conductive RF shielding materials designed to deflect cell phone radiation away from your body.    Testing the conductivity of shielding material inside the QuantaCase™ is an inexpensive way to verify the material being used supports the physics necessary to reflect microwaves and provides a conductive barrier between your Samsung Galaxy S21 and your body.

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™ 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 Samsung Galaxy S21 smartphones

The RF Safe QuantaCase™ only incorporates shielding mechanisms that utilize deflection.  Absorption (attenuation) is never used to prevent affecting the Samsung Galaxy S21 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™ 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™ deflects Samsung Galaxy S21 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.
