2AMERICAN MUSEUM OF ATOMIC ENERGY NEUTRON IRRADIATED 1952 ROOSEVELT SILVER DIMES

Description: This American Museum of Atomic Energy Neutron Irradiated 1952 Roosevelt Silver Dime is a unique addition to any coin collection. There are two enclosed in this deal. The pictures are of the actual coin(s) that you will receive. The coin features a business strike type, with a fineness of 0.9. It is ungraded and uncertified, and conditionally a rare find for collectors. The coin is composed of silver and are encased (immediately after irradiation). It was minted in the United States in 1952 and is a great way to commemorate the historic use of atomic energy, as intended by the museum. This coin is a must-have for any collector or history enthusiast. If the process of irradiation is new to you please read the documents in the pictures. The pictures can be emailed to you through Ebay upon purchase, by request. In a 1954 press release from the Museum of Atomic Energy: "The irradiator works as follows: A mixture of radioactive antimony and beryllium is enclosed in a lead container. Gamma rays from the antimony are absorbed by the beryllium atoms and a neutron is expelled by the beryllium atom in the process. These neutrons, having no electrical charge, penetrate silver atoms in the dime. Instead of remaining normal silver-109, they become radioactive silver-110. After irradiation, the dime is dropped out through a slot in the lead container and rests momentarily before a Geiger tube so that its radioactivity may be demonstrated. It is then encased in the souvenir container. Radioactive silver, with a half=life of 22 seconds, decays rapidly to cadmium-110 (In 22 seconds, half of the radioactivity in each dime is gone, in another 22 seconds half the remainder goes, and so on until all the silver-110 has become cadmium)/ Only an exceedingly minute fraction of the silver atoms have been made radioactive." And more about the copper in the dime, as well. These documents are included in the pictures enclosed. The coin will be shipped in a bubble lined envelope by USPS mail. Postage cost is $3.50 which is less than the actual cost.
