How much does distance really matter when it comes to phone radiation? This calculator shows how quickly exposure drops as you move your phone away from your body. Enter your typical distance (ear, pocket, hand, speakerphone), daily use time, and – if you want – your phone’s SAR rating. You’ll get a simple relative exposure score, a daily dose estimate (for comparison over time), and quick comparisons at common distances like 1″, 6″, and 12″.
This tool is educational and uses a distance-based model to illustrate practical changes you can make every day (like using speakerphone or holding the phone a bit farther away).
📱 Cell Phone Radiation Distance Calculator
Estimate a relative exposure score based on distance, daily use, and (optionally) your phone’s SAR value.
Tip: Set 0″ for direct contact (ear or pocket). Even a few inches can reduce estimated exposure significantly.
If left blank, we use a neutral baseline. SAR is measured under lab conditions; this tool is for educational comparison only.

Disclaimer
This tool estimates relative exposure using a distance-based falloff model (with a small near-field adjustment). Results are illustrative, not absolute, and not medical advice. For precise readings, use a calibrated meter.
