Information Sources

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Actinium. Additional text was taken directly from USGS Actinium Statistics and Information, from the Elements database 20001107 (via [http://www.dict.org dict.org), Webster's Revised Unabridged Dictionary (1913) (via dict.org) and WordNet (r) 1.7 (via dict.org). Data for the table was obtained from the sources listed on the subject page and Misplaced Pages:WikiProject_Elements but was reformatted and converted into SI units.

Hypothetical Application of Actinium

In principle, actinium 227 could be used as a source of thermoelectric power. It has a half life of 21.773 years and emits approximatly 56 J/s per gram of actinium 227 (this calculated energy release takes into account decay produts at equlibrum, assumes no gamma rays, assumes all alpha rays emmited have the same energy, and that all beta rays emitted have the same energy).

Actually, the energy emmitted per gram of actinium in equilibrum can be calculated to be approximatly 10 watts per gram with improved data, but this is still approximate and uncertain.
