What to give your Russian-political-dissident-running-away-from-Putin friend?
How about this: Polonium Pen by Charles Wenzel of Techlib. It's basically a portable ion chamber hooked up to an LED light. The gadget will detect radioactive elements in your food and drinks.
Note, if you DO have such a friend, I suggest you don't dine with them frequently if at all.
does this mean that they will have to go back to the 'poison umbrella' trick? http://www.portfolio.mvm.ed.ac.uk/studentwebs/session2/group12/georgie.htm
