alt Hacker NewsAt first I thought this was just a toy, until I got to the Polonium-210. Holy cow. Wikipedia calls it "highly radioactive" and "extremely dangerous to humans" and says that "has the ability to become airborne with ease." Wonder how many kids managed to ingest it. This is the stuff that was used to poison Alexander Litvinenko.
But it was just "minute traces."

Likely zero, as it was encapsulated with resin. They would have had to grind the ring to dust and then eat the whole damned thing.
It was also commonly in record and camera cleaning brushes, as it could be used to induce a static charge, which would attract dust. Likewise, encapsulated, so the risk with normal use was minimal, but again, if you ground the brush to dust and ate it, all bets are off.
Plenty of strange things were sold.
