It might, but the effects would only appear several wavelengths away (like hundreds of feet at 18MHz) > If the power source is really RF he could look for the shadow by making a > second apparatus and moving it around the first apparatus. Or surround it with a grounded faraday cage. Or use a shortwave receiver, looking for really strong ~18MHz stations and perhaps see if it's modulated signal. I'd think it would be easier to offer far stronger evidence: see if the device works in other buildings. RF sources are going to be local. Hey, maybe the device will still work if "grounded" to a metal car body while the device sits outside the car on the hood. Then just drive around at night and see if the LEDs get dimmer.
