Anyone retarded enough to think that 5G is going to kill them and that a magical necklace can protect them from 5G deserves to get cancer from said necklace. Enjoy your thorium oxide laden necklaces retards.

A Geiger counter should be able to sort it out.

Aha! Notice that said "radioactive" but not "ineffective"!

Seriously, though, anyone who thinks anything short of a faraday cage will keep them safe from 5G crap is reflective of the sad state that our (((education))) system leaves us in in regards to dealing with the real world.
