Useful for calculating today's activity for any radioactive isotope. You may also back decay sources to find out the original activity (or for any date), knowing the current activity. If the isotope that you wish to decay is not on the drop down list, check the 'not listed' check-box and manually enter the isotope name and its half-life to ...

Radioactive decay (a.k.a. "nuclear decay", "radioactivity") is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, gamma ray, or electron in the case of internal conversion. ...
While random at the individual level, radioactive decay is predictable over a group of particles with some uncertainty. It is an exponentialprocess, meaning that the quantity of matter decreases at a rate proportional to its current value. The chart below shows an example in which the half of the particles decay each second and the plot reflects th...
The formula for calculating the time elapsed from the beginning of the decay process to the current moment, or a chosen moment in the future, relative to the beginning of the decay is calculated using the formula: where t is the elapsed time, t1/2 is the half-life of the particle, N0 is the quantity in the beginning, and Nt is the quantity at time ...
You can find the half-life of a radioactive element using the formula: where t1/2 is the half-life of the particle, t is the elapsed time, N0 is the quantity in the beginning, and Nt is the quantity at time t. This equation is used in the calculator when solving for half-life time.
The applications of half-life calculation and exponential decay are many, as it has uses in electrostatics, chemical reaction rates, geophysics, archeology, fluid dynamics, heat transfer, optics, luminescence, pharmacology and toxicology, thermoelectricity, vibrations and, of course - radioactivity. There are even applications in finances and routi...
