Wow! If you know that the 1950s' kids can play with uranium ore! The Gilbert U-238 Atomic Energy Lab from 1950 early. "This was the most elaborate Atomic Energy educational set ever produced, but it was only only available from 1951 to 1952. Its relatively high price for the time ($50.00) and its sophistication were the explanation Gilbert gave for the set's short lifespan. 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." Other Gilbert sets (e.g., the No. 11 Atomic Energy set) continued to carry the spinthariscope, the ore and the manual. In addition, the Geiger counter could be purchased separately. " |
