Have you ever wondered how much EMF exposure you’re getting when your laptop is resting directly on your lap? This calculator helps you find out – and shows just how quickly exposure drops when you make a few small adjustments.
Simply enter how long you use your laptop each day, how close it sits to your body, and whether you use any EMF-shielding products. The calculator then estimates your relative exposure score and compares it to safer setups, like keeping your laptop on a desk or using a shielded pad.
You’ll also see exactly how much exposure you could reduce by combining distance and shielding – for example, using a stand to lift your laptop 8–12 inches or adding a DefenderShield® Laptop Shield or EMF-Harmony Harmonizer.
The goal isn’t to scare you – it’s to give you perspective. EMF strength falls off quickly with distance, so small daily changes can make a big difference in your long-term exposure and overall peace of mind.
