Radioactive Decay Law. When an individual nucleus transforms into another with the emission of radiation, the nucleus is said to decay. 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.
Radioactive Decay - Definition | Radioactive Decay Law ...
The radioactive decay law states that “The probability per unit time that a nucleus will decay is a constant, independent of time”. It is represented by λ (lambda) and is called decay constant. The mathematical representation of the law of radioactive decay is:
Radioactive Decay Law | Equations & Examples | nuclear …
The radioactive decay law is an universal law that describes the statistical behaviour of a large number of nuclides. As was written, radioactive decay is a random process at the level of single atoms. According to quantum theory, it is impossible to predict when a particular atom will decay.

The radioactive decay law states that the probability per unit time that a nucleus will decay is a constant, independent of time. This constant is called the decay constant and is denoted by λ, “lambda.”
Radioactive decay - Wikipedia
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma decay.
The Law of Radioactive Decay - Purdue University
The law of radioactive decay predicts how the number of the not decayed nuclei of a given radioactive substance decreases in the course of time. The red circles of this simulation symbolize 1000 atomic nuclei of a radioactive substance whose half-life period (T) amounts to 20 seconds.
