Abstract
The Actinium 235 series is one of the radioactive series which is widely used as a raw material for reactors and nuclear activities. The existence of this series is found in several countries such as West USA, Canada, Australia, South Africa, Russia, and Zaire. The purpose of this study was to determine the activity value and the number of radioactive nucleus decay atoms on the actinium 235 rendered in a very long decay time of 4.3 x 109 years. The decay count in this study uses an algebraic matrix method to simplify the chain decay solution, which generally uses the concept of differential equations. The solution using this method can be computationally simulated using the Matlab program. This study indicates that the value of the decay activity experienced by each element in this series is the same, which is equal to 2,636 x 1011 Bq. This condition causes the actinium 235 series to experience secular equilibrium because the half-life of the parent nuclide is greater than the nuclide derivatives. The decay activity of the radioactive nucleus under the actinium 235 series is strongly influenced by the half-life of the nuclides, the decay constants, and the number of atoms after decay
Highlights
The actinium series is one of the natural radionuclide series formed from the decay process of the radioactive element Uranium-238
Based on the data analysis previously described, several conclusions were obtained as follows: (1) The numerical solution of the number of decay atoms in the Actinium 235 series explains that the highest number of decay atoms occurs in the parent nuclide, which is 2,695 x 1020 atoms
The number of atoms of this decay is influenced by the number of atoms before decay and the decay constant (λ)
Summary
The actinium series is one of the natural radionuclide series formed from the decay process of the radioactive element Uranium-238. This series is one of the types of elements that still exist in nature, even though the amount is not as much as Thorium and Uranium's elements. The decay stage of this series starts with Actinium-235 and ends at the stable actinium, namely Timbal-207. The Actinium 235 series is used as raw material in Nuclear and actinium installations. The fuel is part of the uranium series, where the production of this fuel comes from pure natural uranium (Uranite), which is processed into
