Who didn’t dream of striking it rich in uranium, helping the nation build its nuclear arsenal for fun and profit? The ‘electric’ part of the game was a Geiger Counter used to determine whether a player had hit uranium or not. While I wouldn’t put it past 1950s America to put real radioactive material into children’s toys, it looks like this was more of an ‘Operation’-style electric circuit. Some nice photos and explanation here. (Also a nice 50s/60s RISK game.)
