Radioactive Decay Calculator

The radioactive or nuclear decay takes place, when an unstable atom loses its energy by emitting radiation like alpha, beta, and other particles. These radiations can enter into human skin and damage cells, hence they are dangerous. The elements greater than 83 in the periodic table are radioactive elements and can be found using radioactive decay calculator. Select the element, initial number of moles, time period, the nuclear decay calculator finds the remaining moles of nuclei.

Formula:

c = (1000 x a x e-(log 2 / d) x b ) / 1000 Where, c = Moles of Nuclei Remain a = Initial Number of Moles of Nuclei b = Time Period d= Element

Example:

Find the remaining moles of nuclei for the element uranium-238, where the initial number of moles is 100 and the time period is 34 days.

Solution:

c = (1000 x 100 x e-(log 2 / 32) x 34) / 1000
=100 moles of nuclei remain.
