Okay but assuming there's no exposed metal parts, is one of these radios with a polarized cord really more dangerous than a regular old two pronged lamp with a polarized cord? If you plug that lamp into an outlet with positive and neutral wired wrong you will have mains voltage on the light bulb threads and socket threads instead of ground, and that's gonna be pretty unsafe for anyone changing the bulb. But lamps are so common, we don't even think about them as safety hazards.
