Outside of a Geiger-Mueller counter, which is used to detect radioactivity, what is a device I could use to monitor the level of radiation given off by electronics such a cell phones, monitors, WiFi and other such things?

I am curious how much radiation I am being exposed to when sitting at my desk surrounded by electronics and over the years I have always wondered how much radiation a computer gives off, especially these newer ones with high end components.

Does anyone know of any device that will detect this kind of radiation? What would be the name for this kind of radiation? Computers whistle and put off high frequency noises due to the high speed fans and other such things and very few people even seem to care how much radiation they are exposing themselves to. Seems to me some kind of detection unit would be widely available.

I currently have a breathalyzer that I administer to the wife when she gets shitfaced and tries to deny she is drunk... it was pretty cheap online and it's nothing real special or accurate but when someone is loaded it always pegs the relatively small threshold and calls them out. Anything over 0.5 BAC makes it go off. There has to be something like this to measure frequency radiation or whatever it is electric devices put out. I am convinced we have reached a critical level for such things as more and more devices surround us!

Thanks in advance!
