ASUS Motherboard Reduces Radiation by 50%

Now What?!?

Green Motherboards—Protect 3.0
Motherboards are the heart of the system, and ASUS Green Design has come up with a new standard in motherboard protection with ASUS Protect 3.0. Protect 3.0’s EMI and Anti-Surge features protect users and their systems—reducing radiation exposure by up to 50 percent and preventing electrical surges from damaging the system.


What is the Radiation Exposure aspect of this?

Are you saying a motherboard produces a significant release of radiation (x, alpha, beta, gamma) during normal operation?

Or are we speaking of radiated heat and someone didnt get the translation correct?

Can you just make a claim and stick a green logo on anything these days and charge more in the name of mother earth?

Even if a MB somehow produced radiation , can it even escape a computer case if it is at ultra low levels which i would suspect if at all proven.

"Are you saying a motherboard produces a significant release of radiation (x, alpha, beta, gamma) during normal operation?"

Hu man, you seem to mix different things. The radiations you're talking about are ionizing radiations, those that transform the matter by ionization. The article is talking about non-ionizing "rays", commonly named... electromagnetic waves. And it happens the vector of those radiations is just a photon.

Maybe you think also that only devices with an antenna can radiate EM waves. That's not the case and by the way, an antenna can just be anything, like a simple wire, which is actually used in some case (long waves antenna). By the way, antennas are just wires that are somehow optimized in size and shape for a better result at the frequency they will be used. Any electronic component radiates and generate an EM field in its neighborhood. Just most of the time this EMF is insignificant at "normal" distance. Note that the "strength" of an EMF is divided by 4 each time you double the distance the source and the "receiver". So two important factors are: radiated initial intensity and distance to source.

CPU, GPU, and other MoBo components happen to work with high frequency currents, and sometime high intensity, as demonstrated by the need to cool them and the size of the power supply. CPU that works at 2 GHz, meaning their clock is a square signal at 2 GHz, also radiates at this frequency, and by the mean of "frequency products" radiates at other frequencies, but at a lower level (heterodyning and harmonics), GPU are like CPU, RAM also radiates.

Understanding EMF means understanding how an emitter works. You may discover if you search that to produce an EMF, you need to have an oscillator to produce a non-radiated signal, and then to radiate this signal. So the question is: do we have those components in a PC? Yes we have them.

A clock is just an oscillator, pure and simple. A low power one. This clock will drive all the functions on the MoBo, meaning this low power signal can potentially by amplified.

Can we radiate this signal off the MoBo? Yes we can. Specially at those frequencies (2 GHz), anything becomes an antenna: a wire, a printed board, a metallic surface... name it.

Can this radiated signal reach the outside of the Desktop or Laptop? Depends, but yes, at least partially in the best case, and totally in the worth. The metallic casing will acts somehow like a Faraday case, but not a perfect one. EMF will be re-radiated by any connection (power cord, network cable, monitor cable, etc). Sometimes basic "filters" are found on the cables to avoid those re-radiation (ferrite cores). If you chose to have a transparent casing, then you're out of luck... no protection.

The problem is to understand whether the EMF are significant or not, and I'm also interested in this aspect. And in spite I can understand what is a radio-emitter and receiver (I've built some), I don't have the answer.
