Most people would never know, if it wouldn’t be for every gold-related company having a vested interest in making people scared of it.

Plus, 20 years is really not very long for it to be completely harmless; just ask the world’s supplies of whiskeys that really only start to have any value after 10+ years.

Industrial gold demand for use in electronics is about 250 tonnes per year. Much of that likely doesn't care about slight radioactivity?

Maybe you wouldn't use that gold for bond wires (but they are less used now and mostly copper AFAIK).

I agree with you, but people can also be very irrational about the value of gold.
