You gotta remember that you're dealing with idiots who tremble at even a hint of an idea that radiation is near them. In fact, there's a little device in your car (assuming it's powered by gasoline) where it's name was determined due to the fear of radiation. The "catalytic converter" has that name because of idiots who fear the concept of radiation. The correct proper name for that device is "catalytic reactor". But the word reactor is used in nuclear reactors so "obviously" a "catalytic reactor" is dangerously radioactive and should never ever be placed in a car because it might spread radiation all over the place and don't even think about what would happen in an accident. Because of that fear, engineers call that little device a "catalytic converter" because that doesn't have the dangerous radiation inducing effects that the word "reactor" has.
Remember your audience and compensate for their ignorance and/or stupidity.
It's a chemical reactor, not a nuclear one. Catalytic activity is a chemical phenomenon, not nuclear.
Strangely enough I can't recall any mention of the 3.46.
That's likely because there wasn't one. It went from 3.1 to 3.5 to 3.51.
