Or even more surprising hazards.

The token on the left in that picture was issued in 2003 by postal  
mail to a Sloane Digital Sky Survey collaborator at the US Naval  
Observatory. All incoming packages were subjected to high doses of  
electron and x-ray radiation, as it is also the residence of the Vice  
President.

On the right is the normal appearance of the token and its holder.
