How to reduce electromagnetic emissions?

[bluepuma77]

It might sound finicky, but I would like to reduce the electromagnetic emissions from the RFID reader.

I build a speaker with an RFID reader inside and kids are putting their heads on it, I don't want their brains to be fried over time. (Mobile phone usage [GSM, UMTS, LTE] is strongly discouraged for small kids.)

It there a way to reduce 1) the field strength and 2) the emission interval? I would be happy to experiment to set the strength as low as possible and for me a 3 second interval would be enough. I am just a RFID user, so I am to sure if this is doable at all.

Not sure if you're trolling, but I'll try to be nice: The electromagnetic emissions from this device have both lower per-photon and total energy than sunlight, by multiple orders of magnitude. I hope you don't leave your kids locked in a cellar considering visible light is more "dangerous" than this.
