Only available from 1951–1952, the Gilbert U-238 Atomic Energy Lab science kit for CHILDREN included four types of uranium ore, a Geiger counter, a comic called Dagwood Spits the Atom and a coupon for ordering MORE radioactive materials. One of the four uranium ores included was Po-210 (Polonium) which, by mass, is 250,000 times more toxic than hydrogen cyanide.
Just one of 8 banned children’s toys from yesteryear.
