>>16721I would avoid wireless mice, game-pads and keyboards, because after a few years the battery will fail and if you can't replace it, the devices become unnecessary landfill. (Assuming that you are not willing to pry open devices to solder in a new battery pack). The wireless connections of these devices can also be hacked
But it's not going to give you cancer, super low power non-ionizing radiation can't knock atoms off the polymer chains that make up your DNA.
Just get wired peripheries, if you really have to have wireless get stuff that has user replaceable batteries.
