How to build EMF radiation protection
If you ask pretty much anyone the EMI radiation from your laptop is not likely to do you any physical damage.

Having said that, someone somewhere will likely expose some rats to a ridiculous amount of radiation and the rats will get sick, and they will claim laptops cause cancer... So in reality, you can't claim anything is safe.

However, fretting about it, can make you sicker than the radiation itself. As such, if it worries you, I suggest a quick and cheap solution.

Go visit your local hardware store and buy a sheet of foil-backed foam insulation, like silverboard.



It comes in big sheets so you can make a few lightweight laptop sized "trays" that you can use to not only provide an EMI shield, but also stop the heat from the laptop from cooking your legs.
