WEBSep 12, 2022 · Radioactive decay occurs for all nuclei with Z > 82, and also for some unstable isotopes with Z < 83. The decay rate is proportional to the number of original (undecayed) nuclei N in a substance. The number of nuclei lost to decay, − dN in time interval dt, is written. − dN dt = λN.

WEBRadioactive decay law: N = N.e-λt The rate of nuclear decay is also measured in terms of half-lives. Radioactive material with a short half-life is much more radioactive (at the time of production) but will obviously lose its radioactivity rapidly. The half-life is the amount of time it takes for a given isotope to lose half of its radioactivity.

WEBJan 22, 2021 · In analyzing a radioactive decay (or any nuclear reaction) an important quantity is Q, the net energy released in the decay: \(Q=\left(m_{X}-m_{X^{\prime}}-m_{\alpha}\right) c^{2} \). This is also equal to the total kinetic energy of the fragments, here \( Q=T_{X^{\prime}}+T_{\alpha}\) (here assuming that the parent nuclide is at rest).

WEBRadioactive decay is the process in which an unstable nucleus spontaneously loses energy by emitting ionizing particles and radiation. This decay, or loss of energy, results in an atom of one type, called the parent nuclide, transforming to an atom of a different type, named the daughter nuclide.
