The actinium series, known also as the actinium cascade, is one of three classical radioactive series beginning with naturally occurring uranium-235.This radioactive decay chain consists of unstable heavy atomic nuclei that decay through a sequence of alpha and beta decays until a stable nucleus is achieved. Ac 225 is used in the field of medicine as an agent for radiation therapy. Interesting Facts. ; It is about 150 times heavier than radium [4]. Answer has 1 vote. Due to this similarity the separation of actinium from lanthanum and the other rare earth elements, which are also present in uranium ores was difficult. References. Mining of actinium from uranium ores is not feasible since actinium concentrations in these ores are very small; most actinium used today is artificially produced. Facts about actinium 4: Occurrence in Nature. The chart below shows the calculated isotope pattern for the formula AcI 3 with the most intense ion set to 100%. Targeted Conditioning and ARC Pipeline. One of its isotopes is sourced from californium-253 through the process involving nuclear reactors. Bulk properties. This whole disintegration chain with its branches is called the actinium series. Actinium-227, which is one of the decay products of uranium-235, has a 21.8-year half-life and in turn decays almost entirely to thorium-227, but about 1 percent decays to francium-223. The electronegativity of Actinium is: χ = 1.1. Looking for online definition of actinium or what actinium stands for? Symbol: … ... For search terms, we used combinations of the key words "health," "water," and "radioactivity." For this purposes, a dimensionless quantity the Pauling scale, symbol χ, is the most commonly used. Ac is the chemical symbol for actinium. Actinium is a white colored metal that gives off a blue light. Actinium has no biological use. actinium meaning: 1. a chemical element that is a soft, silver-white metal and is radioactive: 2. a chemical element…. For this purposes, a dimensionless quantity the Pauling scale, symbol χ, is the most commonly used. In case of actinium series, the stable nucleus is lead-207. It can be applied to produce Bi-213 in a reusable generator or can be used alone as an agent for radiation therapy, in particular for targeted alpha therapy (TAT). Actinium can also be artificially produced. Actinium Pharmaceuticals Inc is a biopharmaceutical company engaged in the development of innovative-targeted therapies for patients with cancers lacking effective treatment options.
