Good grief! I guess a paper mask will do! After all, it will stop viruses, so it must also stop radiation! No sweat! If you are in the middle of a building and the building collapses, THEN put the paper mask over your head like a hat and you will be OK!

P.S. Does our wonderful government and our delightful President know something about what is coming that we don't know? Remember that the Bible is very clear that "sudden destruction" accompanies the Rapture (end of 1 Thess. 4 and the beginning of 1 Thess. 5).
