Actinium nuclear properties

In this appendix we now reproduce, for reference and comparative purposes, the tables in each of chapters 2 through 13 that contained details of the nuclear properties of the isotopes of actinium through lawrencium and of elements 104-109. We then give a table summarizing the specific activities of the nuclides. 

The seventh-period inner transition metals are called the actinides because they fall after actinium, Ac. They, too, all have similar properties and hence are not easily purified. The nuclear power industry faces this obstacle because it requires purified samples of two of the most publicized actinides uranium, U, and plutonium, Pu. Actinides heavier than uranium are not found in nature but are synthesized in the laboratory.
