Chapter 1: Introduction to Electromagnetic Fields (EMF)

Electromagnetic fields (EMF) are all around us. They are produced whenever electricity is generated, transmitted, or used. These invisible fields result from the interaction between electric and magnetic fields.

EMF in Our Daily Lives

EMF exposure comes from:

  • Power lines
  • Mobile phones
  • Wi-Fi routers
  • Bluetooth devices
  • Televisions and radios
  • Microwave ovens
  • Computers

EMF and the Digital Age

The digital transformation of society means we’re constantly surrounded by electronic devices. This has raised awareness and concerns about the potential health impacts of long-term EMF exposure.


Chapter 2: What is a Radiation Detector – EMF Meter App?

The Radiation Detector – EMF Meter App is a smartphone application that utilizes your device’s internal sensors to detect and measure EMF radiation. These readings help users assess electromagnetic pollution levels in their surroundings.

Main Purpose

  • Detect hidden EMF sources
  • Visualize exposure levels
  • Create safe spaces (especially bedrooms, workspaces)

Chapter 3: The Science of EMF Detection

Electromagnetic Spectrum

The EM spectrum ranges from:

  • Extremely Low Frequency (ELF) – power lines
  • Radiofrequency (RF) – mobile phones, Wi-Fi
  • Microwave – microwave ovens
  • Infrared, Visible Light, UV
  • Ionizing Radiation – X-rays, gamma rays

Units of Measurement

  • Microtesla (μT)
  • Milligauss (mG)
  • Volts per meter (V/m)

1 μT = 10 mG

What Do the Numbers Mean?

  • 0–1 μT: Safe
  • 1–25 μT: Slightly elevated
  • 25–50 μT: Caution
  • 50+ μT: High exposure (limit time spent)

Chapter 4: Mobile Technology Used in Detection

Sensors Used

Most EMF apps use:

  • Magnetometer – detects magnetic field strength
  • Accelerometer & Gyroscope – sometimes used for motion tracking
  • Compass sensors – used for direction of EMF fields

The magnetometer is key. Not all phones have one. Use a compass app to check.

Sensor Calibration

Calibrate your sensor by:

  • Moving in figure 8
  • Rotating your phone on all 3 axes
  • Doing it in a “clean” space without EMF interference

Chapter 5: Core Features of the App

Real-Time Readings

Live measurements of EMF levels near your device.

Color Indicators

  • Green – Safe
  • Yellow – Mildly elevated
  • Red – High risk

Graphs & History

Track EMF over time via dynamic charts.

Alerts

  • Set threshold for automatic alarms
  • Beep or vibration when EMF spikes

Export & Logging

Save data to CSV, share via email or upload to cloud.


Chapter 6: How to Use the Radiation Detector – EMF Meter App

🛠️ Step-by-Step Guide

  1. Install the app from Play Store or App Store.
  2. Open the app, allow required permissions.
  3. Calibrate sensors away from devices.
  4. Scan your room, especially beds, tables, and walls.
  5. Note high readings, mark danger zones.

Clean Measurement Tips

  • Remove phone case
  • Avoid magnets or metal surfaces
  • Keep still for steady readings

Chapter 7: Use Cases in Daily Life

In the Bedroom

  • Check if Wi-Fi router or smart devices emit high EMF
  • Adjust bed placement

Baby Care

  • Scan baby crib, monitor devices, and toys

Offices

  • Identify radiation near computers or power sources

Home Safety

  • Check microwaves, TVs, smart meters

Ghost Hunting!

Paranormal investigators use EMF apps as ghost detectors (based on field spikes near “energy”).


Chapter 8: Benefits of EMF Meter Apps

  1. Awareness: Know what’s around you.
  2. Preventive Health: Reduce long-term exposure.
  3. Educational: Great for science classes or student experiments.
  4. Cost-effective: Cheaper than physical EMF meters.
  5. Portable: Carry it in your pocket.
  6. Easy to use: No technical knowledge needed.

Chapter 9: Limitations of App-Based EMF Detection

  1. Limited Sensor Capability
  2. No RF Radiation Detection
  3. Affected by magnetic phone covers
  4. Environmental Interference
  5. No Ionizing Radiation Detection

Pro Tip:

For high precision or medical-grade detection, use certified hardware EMF meters.


Chapter 10: Best Practices for Accurate Detection

  • Use multiple apps for comparison
  • Keep phone away from metal surfaces
  • Run tests at different times of the day
  • Keep logs for EMF mapping
  • Compare with physical EMF meter (if available)
