Much of what I am going to write in this post is based on what I have read and understood (with very, very limited knowledge of the subject) on the Internet. So, if I have been misinformed or I have misunderstood anything, please don't hesitate to correct me. I would appreciate it.

As the title of the thread suggests, my question is to do with electromagnetic waves being emitted from my PC. I have come to understand that they can do me great harm physically and, as I spend a lot of time next to my Pc, I have been looking to see if I can reduce these effects.

One of the ways that I've been looking at is to try and construct some sort of Faraday cage around it. I know that this system is said to work when trying to protect a Pc from electromagnetic attacks and so I am wondering if the reverse would be true and so by constructing a Faraday cage around the Pc I would catch the electromagnetic emissions from it.

Something else I've read is that for a Faraday cage constructed from wire mesh to work the gaps in the mess must be smaller than the height of the waves. I have considered constructing one from sheet metal but that seems a bit extreme and would be very costly.

So my question is, does anyone know what the height of the electromagnetic waves coming from my Pc is?

Many thanks in advance for any help.

Just one more note, if you haven't already realised, my knowledge of physics and so forth is extremely elementary so please, keep it simple! I really would appreciate it.
