Classic Toy from a Classic Time

Welcome to The Gilbert U-238 Atomic Energy Lab from 1951.
This was the most elaborate Atomic Energy educational set ever produced, but it was only available from 1951 to 1952. It had a high price for the time ($50.00) and today, it is so highly prized by collectors that a complete set can go for more than 100 times the original price.
The set came with four types of uranium ore, a beta-alpha source (Pb-210), a pure beta source (Ru-106), a gamma source (Zn-65?), a spinthariscope, a cloud chamber with its own short-lived alpha source (Po-210), an electroscope, a geiger counter, a manual, a comic book (Dagwood Splits the Atom) and a government manual "Prospecting for Uranium."
