In the modern age, electronic devices like laptops, tablets and cell phones all emit Electromagnetic Radiation (EMF), and to avoid it would be impossible. However, it is possible to mitigate the risks and decrease your exposure levels – thanks to physics!

Quick Re-cap of Physics

Because of the nature of energy, radiation is exponentially stronger the closer you are to it. Its strength actually decreases radially as you move away from it. In physics, it follows the inverse-square law.

The intensity is proportional to 1/distance squared.

Inverse Square Law

This means if you are 2 inches away from the source, you experience 1/4 the amount of radiation exposure as you would if you were just 1 inch away from it. If you are 4 inches away from it, you now experience 1/16 the amount of radiation you would have if you were just 1 inch away. This is why a lot of cell phone manufacturers recommend you keep your cell phone at least several inches away from your body at all times.

To protect yourself from Electromagnetic Radiation, you have 3 highly effective options:

  1. Time of exposure
  2. Distance from exposure
  3. Shielding yourself from exposure

Option 1: Time

Radiation exposure takes time to have an effect. It is a trickling stream of energy that can effect changes on cells subtly over time. Short exposure may not affect the same level of change on your body as long-term exposure would. Take advantage of this by turning on your cell phone only when you need it. Turn your computer on when you use it. Take breaks from using your devices when possible. The chart below demonstrates ionizing-radiation exposure over time but also applies to non-ionizing radiation, which works the same way.

Option 2: Distance

The farther you are away from a radiation source, the less exposed you are to its power. If you want to protect yourself, you should keep at least some small distance between you and the source of the radiation. Even a small increase in space between you and your cell phone or tablet, etc. can make a tremendous difference. That’s because radiation follows the inverse-square law. The laws of physics cannot be beaten!

Option 3: Shielding

It is possible to guard against Electromagnetic Radiation from electronic devices, by using a radiation shield that can deflect, divert, and absorb the radiation that’s between you and the source. The amount of shielding or type of shielding you need to protect against different types of radiation depends on how much radiation the source emits.


You have several options to choose from for protecting yourself and your loved ones. If you feel uncomfortable with Electromagnetic Radiation exposure, you should educate yourself. Take steps to make yourself feel more comfortable.

Ultimately, you decide if it is worth protecting yourself from Electromagnetic Radiation exposure. It is up to you. You decide what makes you feel safe when surrounded by electronic devices is so commonplace.

Electromagnetic Radiation is energy. It can have a profound effect on cells over time. Research is still being conducted on a continuous basis to fully grasp the long-term effects of non-ionizing Electromagnetic Radiation exposure. In the interim, we invite you to learn more.
