Get a small neon bulb, stick it on the end of a non-conductive rod and hold the lamp close to whatever appliance you are concerned about - this is a quick and simple check for electronic radiation, and when compared against the results from a calibrated instrument was reasonably accurate.
If the lamp glows you have a problem with that appliance - if it glows brightly you have a serious problem with that appliance or fixture.
