Ac-225 daughters abundance of emissions and those having energy greater than the CR threshold.

The alpha-emitting radionuclide Ac-225 has been identified as a strong producer of CR light. Assuming their stable equilibrium with Ac-225, we list the relative activities of the daughters. In this table we also list the characteristics of the daughter radionuclides, their total abundance and their capabilities to produce CR in water and tissue.as - seconds, m - minutes, d - days.
