Fair enough. Now, which level of government are you going to use to do it? If you're going to have your state do it, then all you need is for the legislature to enact that prohibition and make the necessary provisions to enforce it. If you want the national government to do it, then you need to enumerate a power for that, because there is currently no "dangerous substances" power granted to Congress by the States, and enumerated in the Constitution.

And under what Constitutional power do we have a right to ban fissile material? You tell me.

We can ban fissible material from being imported from foreign countries under the Commerce Clause. I told you that already.

Currently there is no enumerated power to ban or regulate fissible material in interstate commerce. Unelected career bureaucrats regulate it anyway, and the end result is that our nuclear industries are crippled, being unable to produce isotopes needed for medical and industrial purposes and leaving us dependent on foreign countries for our supplies.

You cry "We the People have a right and responsibility to ban dangerous substances!", and don't seem to care who does it or how. That's exactly how we ended up with CO2 being declared a "pollutant".
