I thought we already understand that Boric Acid or Borax stops ionizing radiation dead. Taking anything that does NOT include Borax and or Boron doesn't stop the issue.
Also pure Uranium is the least of our problems.. nothing like the Devil's math of making Moxa Fuel Rods and the thousands of isotopes and daughter isotopes in it..
[sarcasm on] Good thing all those rods are still buried.. LOL
