Area code 913 is the telephone area code in the North American Numbering Plan for northeastern Kansas. The numbering plan area (NPA) consists of a small ribbon of eight counties bordering Missouri, an area largely coextensive with the Kansas portion of the Kansas City Metropolitan Area.

Cobalt-60 (⁶⁰Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years. It is produced artificially in nuclear reactors. Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope ⁵⁹
Co. Measurable quantities are also produced as a by-product of typical nuclear power plant operation and may be detected externally when leaks occur. In the latter case the incidentally produced ⁶⁰
Co is largely the result of multiple stages of neutron activation of iron isotopes in the reactor's steel structures via the creation of its ⁵⁹
Co precursor. The simplest case of the latter would result from the activation of ⁵⁸
Fe. ⁶⁰
Co undergoes beta decay to an excited state of the stable isotope nickel-60, which then emits two gamma rays with energies of 1.17 and 1.33 MeV. The overall equation of the nuclear reaction is: ⁵⁹
₂₇Co + n → ⁶⁰
₂₇Co → ⁶⁰
₂₈Ni + e⁻ + 2 γ
