1. Introduction to EMF Radiation
EMF stands for Electromagnetic Field. It’s the invisible energy that surrounds us due to the use of electrical devices. From your smartphone and Wi-Fi router to microwave ovens and power lines, EMF is everywhere.
There are two types:
- Non-ionizing radiation (low-level, e.g., from phones, Wi-Fi)
- Ionizing radiation (high-level, dangerous, e.g., X-rays)
2. What Is the Radiation Detector – EMF Meter App?
The Radiation Detector – EMF Meter is a mobile application available for Android and iOS that uses your phone’s magnetic sensor to detect EMF radiation. It converts raw electromagnetic data into readable metrics (like μT or milligauss).
It’s designed for:
- Detecting EMF hotspots
- Checking electronic devices for radiation leaks
- Educational and health awareness
3. Why Measure EMF Radiation?
Growing concerns about:
- Long-term exposure to radiation from mobile towers
- EMF sensitivity (some people claim symptoms from high exposure)
- Safer placement of routers, devices, or sleeping arrangements
Thus, people use this app to stay informed about EMF levels.
4. Types of EMF Radiation
- Extremely Low Frequency (ELF) – Power lines, appliances
- Radio Frequency (RF) – Cell phones, Wi-Fi, Bluetooth
- Intermediate Frequency (IF) – Computer screens
- High Frequency (HF) – X-rays, Gamma rays
The app mostly detects ELF and RF frequencies depending on your phone’s capabilities.
5. Technology Behind the App
Most phones have a magnetometer sensor, used for compass navigation. The app utilizes this to detect magnetic fields in microtesla (μT) or milligauss (mG).
It doesn’t measure RF radiation like a hardware RF meter, but it provides a reasonable estimate using the magnetic component of EMFs.
6. Key Features of Radiation Detector – EMF Meter App
- Real-time EMF readings
- Graphical interface for trends
- Beep alert when radiation crosses limits
- Logging & Export of readings
- Color-coded EMF zones
- Dark mode & themes
- Sensitivity adjustment
- Built-in compass (optional)
7. How to Use the EMF Meter App
- Download from Play Store/App Store
- Grant necessary permissions (location, sensor)
- Calibrate the device (if needed)
- Point your phone near the suspected device/area
- Read μT values on screen
- Take note of high readings (>50 μT is often considered high)
8. App Setup & Permissions
Permissions Required:
- Magnetometer access
- Location access (for mapping)
- Storage (for logs/export)
Always calibrate the app away from electronics or magnets.
9. Understanding EMF Readings
| Reading (μT) | Risk Level |
|---|---|
| 0–1 μT | Safe |
| 1–25 μT | Low Exposure |
| 25–50 μT | Moderate Risk |
| 50–100 μT | High Risk |
| 100+ μT | Very High (Avoid) |
Note: These levels are not medically certified. Use as guidance only.
10. Real-Life Use Cases

- Cannot detect RF radiation (like mobile tower signals)
- Affected by metallic objects and magnets
13. Best Practices for Using the App
- Calibrate away from electronics
- Avoid magnetic covers or cases
- Use on multiple spots around your room
- Measure at different times of the day
- Compare readings with other apps for accuracy
14. Comparison with Physical EMF Meters
| Feature | EMF Meter App | Physical EMF Meter |
|---|---|---|
| Price | Free / Low Cost | ₹3000 to ₹50,000 |
| Accuracy | Moderate | High |
| Portability | Very High | Medium |
| Sensor Range | Limited (μT only) | Wide (RF, ELF, etc.) |
| Calibration | Manual | Auto & manual |
15. Top Competitor Apps

23.FAQs About EMF Detection
Q: Can my phone detect all types of EMF?
A: No, only magnetic fields via the magnetometer.
Q: Is it safe to live near high EMF zones?
A: Depends on duration, exposure, and distance. Consult experts for chronic exposure.
Q: Can it detect mobile tower radiation?
A: Not directly. RF meters are needed for that.
