A German restaurant owner is under investigation for allegedly marking playing cards with radioactivity to rig games.
Berlin police say the 41-year-old woman daubed Iodine-125 on specific cards, which allowed them to be identified by a cohort with a concealed radiation detector.
Media reports say law enforcement discovered the scam when radioactive card fragments were found during a routine inspection of a garbage truck at a waste treatment plant a year ago. Investigators then followed the vehicle’s route to determine the origin.
They raided the restaurant and other premises earlier this month and discovering 13 radioactive cards. Police note that Iodine-125 is commonly used for medical purposes and only poses a health risk in significant amounts through direct contact with no protective clothing.
Police continue to investigate how much money was won using the practice and how long it has been going on.
Iodine-125 is a radioisotope of iodine and generally used for nuclear medicine imaging and for radiation therapy to treat a number of conditions, including prostate cancer, some melanomas, and brain tumors.
