Free EMF Safety Tools & Calculators

Electromagnetic fields (EMFs) are all around us—from power lines and cell towers to the gadgets and appliances we use every day. At EMF Advice, we’ve created a collection of easy-to-use, science-based EMF tools to help you estimate safe distances, assess exposure levels, and make informed decisions for a healthier living environment.

Explore the calculators below to get personalized EMF safety guidance for your home, office, or property.

Why Use EMF Calculators?

Most people don’t realize how many sources of EMF are present in their daily surroundings. Whether you’re charging your phone next to your bed, living near a high-voltage power line, or working in a smart home full of connected devices, your EMF exposure can vary significantly depending on distance, duration, and device type.

Our EMF calculators are designed to:

  • Help you find the optimal distance from EMF sources
  • Visualize real-world safety zones using color-coded diagrams
  • Provide results based on trusted guidelines like the BioInitiative Report, ICNIRP, and Building Biology Standards
  • Offer practical suggestions for layout, shielding, and exposure reduction

Each tool includes built-in reference data, scientific formulas, and customization options tailored for general users, parents, EMF-sensitive individuals, and health-conscious professionals.

What Types of Tools Are Available?

We’ve developed calculators for both external infrastructure EMF sources and indoor personal devices, such as:

  • Safe distance from cellphone towers (2G to 5G, including mmWave)
  • Power line and substation exposure zones
  • Railway and metro EMF estimators
  • EMF from WiFi routers, Bluetooth gadgets, and smart appliances
  • Combined exposure tools for entire rooms or homes
  • Time-based calculators that show how duration affects cumulative EMF risk

Each tool is fully mobile-friendly, updated with the latest scientific models, and optimized for real-world use.

Who Are These Tools For?

These EMF calculators are useful for:

  • Homeowners, renters, and homebuyers assessing EMF risks before moving
  • Parents optimizing children’s bedrooms and play spaces
  • People with electromagnetic hypersensitivity (EHS)
  • Architects, builders, and real estate professionals
  • Wellness practitioners and health consultants
  • Anyone who wants to take control of their indoor environmental quality

How to Use These Tools Effectively

Start by choosing the tool that matches your concern—whether it’s a gadget, infrastructure, or overall room layout. Input your device or location details, select a safety standard, and review the recommended safe distances.

Each calculator includes:

  • Scientific exposure modeling
  • Visual aids (zones, sliders, diagrams)
  • Practical tips for furniture layout, shielding, and usage timing
  • Options to export, save, or share results

Sources & Scientific Basis

All our tools are grounded in trusted, peer-reviewed scientific literature, including:

Our goal is to make this complex topic approachable, actionable, and transparent for anyone concerned about EMF exposure.
