Yes, because what I was doing was objectively dangerous. Dueling used to be a commonly accepted practice, yes even killing - pity that ladder was pulled up! What about the children's chemistry sets that included uranium, mercury, and cyanide?
I think consensual duels should still be legal. Numerous states have laws about mutual combat where it is perfectly legal to beat the fuck out of each other.
The uranium wasn’t really dangerous, unless you swallowed it. Common U-238 has a half-life of about 4.5 billion years, so it’s not actually very radioactive. The most dangerous thing about it is its toxicity as a heavy metal, but plenty of other elements of a chemistry set are at least as dangerous.
