Radioactive playing cards have been seized by police in Berlin, following a search which has been going on for a year.
Police reportedly started the search after a radioactive material was discovered as part of a routine inspection at a waste treatment centre.
It was then discovered that the radioactive material was on playing cards, according to The Local.
Authorities believe the reason the playing cards were radioactive was because they were part of an illegal scam.
The material would allow a player to recognise which cards were which by using a reader, whilst other players would not be able to spot a difference.
Earlier this month authorities searched a 41-year-old woman's house, restaurant, karaoke bar and club as it was thought she may have been linked to the cards.
The search uncovered 13 radioactive cards, the radiation coming from iodine 125. The amount of iodine 125 used on the cards was not deemed to be dangerous unless someone was handling them, however the radiation found was eight times the legal limit.
Police had suspected the woman after working out the route taken by the truck which brought the cards they already had to the waste centre.
The woman is now being investigated over the matter and if convicted could be handed a prison sentence of up to five years or a fine. It is not yet clear who else was involved in the scam.
