Hi

So you are saying that you are getting a worrying radiation reading? I don't know about radiation levels but I'll assume it is high.

Dials on aircraft used radioactive materials to stimulate light from another material in the paint. The material that converts the radiation into light 'wears out' but the radioactive material doesn't (well, not for a while anyway).

I'm assuming here that when you say that the dial is 'not luminous in any way', you mean that it doesn't glow.

Cheers
James
