![]() The DOE IP has developed and implemented modern stable isotope enrichment capabilities to replenish supplies housed in the National Stable Isotope Repository and promote U.S. to be dependent on foreign sources for certain stable isotopes. inventory of stable isotopes is limited or has even been depleted in some cases, causing the U.S. The latter consists of enriched stable isotopes created by calutrons (electromagnetic ion separation) that were developed as part of the Manhattan Project, the calutrons ceased operations in 1998. The DOE IP manages federal inventories of key isotopes, such as helium-3 for cryogenics and other applications, and the National Stable Isotope Repository. These disciplines are foundational, not only to isotope production and processing, but underpin many critical aspects of basic and applied nuclear and radiochemical science. The R&D activities provide collateral benefits for training, workforce development, and promotion of a future U.S.-based expertise relevant to nuclear energy, accelerator science, nuclear engineering, nuclear physics, isotope enrichment, and nuclear chemistry and radiochemistry. The DOE IP supports world-leading research and development (R&D) associated with creating novel and more efficient isotope production and processing techniques. industry to ensure availability of adequate, high quality isotope supply for continued stability and planned growth and facilitates commercialization of isotope production to the domestic private sector. The DOE IP utilizes particle accelerators, nuclear reactors, enrichment technologies, and radiochemical processing capabilities throughout the national laboratory complex and at universities that it stewards, or leverages capabilities stewarded by other federal programs or academic institutions to most cost effectively utilize national capabilities to meet the requirements of the nation in isotope demand. Isotopes can directly enable emerging technology, and contribute to the economic, technical and scientific strength of the United States. Isotopes are high-priority commodities of strategic importance for the nation and are essential in medical diagnosis and treatment, discovery science, national security, industrial processes and manufacturing, space exploration and communications, biology, archeology, quantum science and other fields. The Program is typically the only, or one of few, global producers for these novel isotopes. The DOE IP produces critical radioactive and stable isotopes in short supply for the nation or that no domestic entity has the infrastructure or core competency to produce. The Program supplies isotopes and related services to the Nation under the Atomic Energy Act of 1954 and has the sole authority within DOE to produce isotopes for sale and distribution. ![]() For Gamma sources, 25mm thick lead is required to absorb 80% of the radiation.The DOE Isotope Program (DOE IP), and its predecessor organizations, has been at the forefront of the development and production of radioactive and stable isotopes that are used worldwide.For Beta sources, about 4 to 6mm thick lead is required for full absorption.For Alpha sources, a thin aluminium sheet provides sufficient absorption.Handle the alpha source with special care to avoid damage to the fragile metallic coating over the material.As general practice, radioactive sources should always be handled with tongs or forceps to keep them at least 30cm away from user.Do not place into pockets of clothing or carry bags etc. Unnecessary handling of sources should be avoided.These school grade radioactive sources have a very low level of activity and do not require licensing, however they should be handled with care. Although radioactivity level is very low, the sources should not be carried around for long periods or placed in pockets of clothing against one’s body. x 5mm thick plastic disc with the symbol printed. The school grade radioactive sources are mounted in a 25mm diam. COBALT 60 (GAMMA PARTICLE): 1.0 uCi or 37 kBq (+/- 10)
