Cobalt-57 (Co-57) is a radioactive isotope of cobalt with a half-life of approximately 271.8 days. It decays by gamma emission and is often used in various scientific and industrial applications due to its stable and predictable gamma-ray emissions.

Emissions below 10 keV or 1% excluded. 2. Always wear protective gloves, a lab coat, and safety eyewear to protect the skin and eyes from. 3. Survey work areas before, during, and after …

Jun 14, 2023 · Cobalt-57 (57 Co) has emerged as a promising radionuclide and as an isotope for diagnostic and calibration sources. Herein, we report the production, chemical separation, and quality control of 57 Co in an RFT-30 cyclotron facility.

Reduce internal and external radiation dose by monitoring the worker and the work area after each use of radioactive material, then promptly cleaning up any contamination discovered. Use the smallest amount of radioisotope possible so as …

Aug 24, 2022 · Cobalt-57 is used as a source in Mössbauer spectroscopy of iron-containing samples. Electron capture by 57 Co forms an excited state of the 57 Fe nucleus, which in turn decays to the ground state with emission of a gamma ray.

Detailed decay information for the isotope cobalt-57 including decay chains and daughter products.

Cobalt-57 (Co-57) ⁵⁷Co is incorporated in a light ceramic matrix and sealed in a welded stainless steel capsule. The Type 27 source is also available in a titanium capsule.
