"used pinball machine parts"? (@Doc Brown, Back to the Future)
I'm thinking similar to Syncopator, it's probably just a bunch of parts that do nothing more than waste energy (drain the battery you plug into it). It looks like they are using an RCA jack and plug for power?? (use find them on stereo equipment for audio connections).
I've never heard of either of those types of radiation. If he's being irradiated by the Earth, then he'd better move to the moon to get away from it.... that makes as much sense as a no-name device that "cures" something no one's ever heard of. Tell him to save his $50 and stick in his sock drawer, it'll do more good for him there than spent on some piece of garbage.
