Household appliance EMF reference
Typical published ranges for common appliances — search or filter, then measure your own equipment for an accurate reading.
| Appliance | Field type | ~15 cm / 6 in | ~60 cm / 2 ft | Notes |
|---|---|---|---|---|
| Electric shaver | Magnetic (ELF) | 4–600 mG | 0.4–10 mG | Wide range reflects motor design differences between models. |
| Hair dryer | Magnetic (ELF) | 1–700 mG | 0.1–10 mG | Field drops sharply within the first foot. |
| Electric blanket | Magnetic (ELF) | 22–39 mG | Not separately reported | Older resistive-wire blankets typically read higher than modern low-EMF designs. |
| Can opener | Magnetic (ELF) | 500–1,500 mG | 3–30 mG | Among the highest close-range readings of common small appliances; used briefly. |
| Electric range / stove | Magnetic (ELF) | 20–200 mG | 0.2–9 mG | Varies by burner, cookware and power setting. |
| Microwave oven | Magnetic (ELF) | 100–300 mG | 1–30 mG | Magnetic-field reading — not a leakage or RF measurement. |
| Television / monitor | Magnetic (ELF) | 10–80 mG | 0.1–8 mG | Older CRT models generally read higher than flat panels. |
| Computer terminal / desktop tower | Magnetic (ELF) | 7–20 mG | 1–3 mG | Varies by internal power supply and proximity to the case. |
| Wi-Fi router | Radiofrequency (RF) | Varies by model and activity | Measure with an RF meter | No comparable published household table exists for RF; strength depends on distance, protocol and data activity. |
| Mobile phone (in use) | Radiofrequency (RF) | Varies by signal and activity | Measure with an RF meter | Output power adjusts automatically to signal conditions. |
| Wireless speaker / smart display | Radiofrequency (RF) | Varies by model and activity | Measure with an RF meter | Typically intermittent, not continuous, transmission. |
| Cordless phone base station | Radiofrequency (RF) | Varies by model | Measure with an RF meter | Some models transmit continuously even when not in a call — check the manual. |

Where these figures come from
Magnetic-field ranges are typical values commonly reported by electric-utility safety pages, which trace back to appliance measurement surveys from the 1990s (the era of the U.S. EPA's "EMF in Your Environment" report). We have not independently re-measured these units. Source example: Liberty Utilities: Understanding Electromagnetic Fields ↗.
RF sources (Wi-Fi, phones, wireless speakers) are shown without specific numbers because no equivalent standardized household survey exists — RF power density depends heavily on distance, protocol and real-time activity. Use our meter selector and an RF-capable meter to measure your own devices.
