Berlin police find radioactive iodine on playing cards

Police raiding a Berlin restaurant have discovered playing cards which had been laced with a radioactive substance.
Detectives believe players could wear a hidden detector on their bodies allowing them to recognise certain cards, giving them an advantage.
The scheme was discovered when a routine check at a waste treatment facility uncovered an increased level of radioactivity in a rubbish truck.
Police managed to trace the vehicle to a restaurant in Berlin.
On raiding it, they found 13 playing cards laced with iodine-125, a substance used in medicine that has a half-life of 60 days.

The German authorities ordered the area to be sealed and cleaned, and say that there is no wider risk of contamination.
