WebbThe constant k is called the decay constant, which controls how quickly the total number of nuclei decreases. The value of the decay constant is specific to the type of decay (alpha, … WebbThis decay gives off energy in a slow process. Half-life After approximately 5,730 years, half of the starting concentration of 14 C will have been converted back to 14 N. The time it takes for half of the original concentration of an isotope to decay back to its more stable form is called its half-life.

WebbRadioactive decay is a random process at the level of single atoms, in that, according to quantum theory, it is impossible to predict when a particular atom will decay. In other words, a nucleus of a radionuclide has no “memory”. There are three basic modes of radioactive decay: Alpha decay .Beta-decay. Gamma decay.
