Slow decaying isotopes
WebbThe basic decay processes are n → p + e - + ν° plus a delayed γ, the two silver isotopes decay to the stable elements 110 Cd and 108 Cd. A chart summarizing the information about the neutron source and silver isotopes is included at the end of this write-up and can be used for an OHP transparency. Setting it up: WebbThis decay gives off energy in a slow process. Half-life After approximately 5,730 years, half of the starting concentration of 14 C will have been converted back to 14 N. The time it takes for half of the original concentration of an isotope to decay back to its more stable form is called its half-life.
