You may have heard that there is a debate whether non-ionizing electromagnetic radiation (or EMF, such as emitted by your cell phone and your WiFi card) is a risk to human health. That is false.
The type of radiation used to enable wireless communication is a form of microwave radiation. The same type of microwave radiation used by microwave ovens to cook.
And so, obviously, it has long been established and accepted that this type of radiation can harm tissue— if it couldn’t, microwave ovens wouldn’t work.
The “debate” (such as it is) over whether radiation from technology like cell phones and WiFi is safe, centers entirely around the question of *what levels of power* of this type of radiation are safe.
At certain levels of power, microwave radiation can heat tissue. This is known as the “thermal effect.”
And, for many years, it was believed that microwave radiation was safe at levels of power insufficient to heat human tissue. This is why the vast majority of regulations governing EMF emissions are designed to protect against the thermal effect.
Today, however, the body of science in this area demonstrates that there are harmful risks to human health at levels far below those required to generate a thermal effect. Regulations that protect against your phone emitting enough EMF to cook your head are important— but they are also vastly insufficient.
Increasingly, it is becoming clear that there is no “safe” level of EMF exposure. Instead, it’s about what degree of risk exists from what types of exposure.
But when you hear or read that there is a debate about whether microwave radiation poses a risk to human health, realize that is simply not true. It is universally accepted that this type of radiation poses real risks to human health; the question is “what risks exist at what levels of this radiation”.
And that’s a big difference.
