Head SAR vs FCC Limit
Moderate (50–80% of FCC limit)
Visualizes head SAR (1.20 W/kg = 75%) against the FCC ceiling of 1.6 W/kg.
Context
What this number means
At 1.20 W/kg, the Pixel 7a's head SAR is on the higher end of currently sold smartphones — about 75% of the FCC's 1.6 W/kg ceiling. It's still FCC-certified and below the legal limit, but reports a higher peak than many other modern phones.
Remember: SAR is a peak-power compliance test against a tissue-mimicking phantom. Your real exposure depends on signal strength, distance from the phone, and call duration. To model actual exposure at distance, try the RADIHALT EMF Calculator.

Practical Steps
Reduce real exposure from your Pixel 7a
Create distance during calls
Use speakerphone or a hands-free option when practical. Keeping the phone away from your head lowers exposure from that source.
Call where signal is strong
A phone may transmit at higher power when the network signal is weak. A stronger signal and shorter calls are simple ways to reduce exposure.
Check the model instructions
Body SAR test spacing can vary by device and test configuration. Use the manufacturer's instructions for this exact model instead of assuming one spacing applies to every phone.
For a laptop or another nearby wireless device at a desk, a conductive layer can reduce RF through the covered path. See how the RADIHALT blanket is made and sized before deciding whether it fits your setup. Phone SAR figures do not measure blanket performance.

Pixel 7a SAR FAQ
Frequently asked questions
What is the SAR value of the Pixel 7a?
The Pixel 7a has a head SAR of 1.20 W/kg and a body SAR of 0.95 W/kg per FCC testing (FCC ID A4RGHL1X). Both values are measured against the U.S. FCC limit of 1.6 W/kg averaged over 1 gram of tissue.
Is the Pixel 7a safe to use?
The Pixel 7a's FCC filing reports head and body SAR values below the U.S. 1.6 W/kg compliance limit under standardized laboratory conditions. SAR is a peak-exposure compliance metric, not a prediction of typical daily exposure or a complete health-risk assessment. Actual exposure varies with signal strength, use, and distance from the body.
How does the Pixel 7a compare to other phones?
At 1.20 W/kg head SAR, the Pixel 7a sits at 75% of the FCC limit. Modern flagship phones typically report head SAR values between 0.80 and 1.30 W/kg.
How can I reduce my Pixel 7a's radiation exposure?
Use speakerphone or wired/Bluetooth headphones during calls, don't carry it directly against skin in pockets, and use it where signal is strong (phones boost transmit power dramatically in weak-signal areas). Try our EMF calculator to model how distance changes your real exposure.
