If the insulation is infinitely thick, there is no outside of the insulation
where radiation can occur.

But, yes, there will be radiation inside the insulation.

And yes there is radiation in the air as I said above but the air is not
infinitely thick.

Like vacuum. But there are ions and free electrons.
In solid and liquid insulators no free electrons.

Does solid insulation makes the radiation weaker or stop it?

I think I see where you're going with this Richard, but you must realize
by now that you're talking to a rock.

To put it another way, he wouldn't pass the Turing Test.

Actually, I am testing the chinese room argument. The operator's
manual appears to be missing some pages.
