Uranium Containing Pencil (ca. 1960)

In 1957, the Kingston Pencil Company received a license from the Atomic Energy Commission that authorized them to possess up to 24 tons of uranium ore. Nevertheless, it seems that their one and only purchase was for 2,400 pounds of ore from the Daybuck Company of Spokane Washington .  The ore was ground up in a rock crusher that belonged to a farmer in Rossville Georgia, and a green dye was then added to the ore to give it a “romantic” appearance. 

Each pencil contained 1.5 to 2.5 grams of 1.7 % ore (ca. 0.02 uCi).  A  memorandum from the Atomic Energy Commission in 1960 estimated that if the entire sample were ingested, the incorporated uranium would only amount to 1/25,000 of the permissible body burden. Nevertheless, that same year the New York Times reported that the Erie County ( New York ) Health Department had ordered the confiscation of similar pencils advertising the Chicken Delight restaurants. The county Health Commissioner claimed that the ore was toxic and “posed a significant hazard if ingested by a child.”  The pencils read “Chicken Delight conduction method has done for the food business what uranium ore has done for AEC.”
