Radioactive Decay 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 ...
Decay Calculator. This Web application will allow you to calculate the activity of a radionuclide after a specified interval of time. The list of radionuclides excludes those with half lives measured in seconds.
Nuclear medicine and medical physics people may use the calculator to ascertain when a diagnostic or treatment isotope has lost its effective strength. A feature that sets this calculator apart from the other online timed decay calculators is its ability to give you the actual calendar date that the isotope will reach the desired activity.
Radioactive Isotopes Decay Calculator. Online calculator that allows you to find out the radiation activity decay in most popular isotopes used in chemistry and medicine. Note: The calculation of radioactivity in minerals is based on certain assumptions.

The time taken for a radioactive element to decay depends on its initial and final mass and the half-life of that radioactive element. Half -life is a characteristic of each radioactive isotope and it ranges from a few fractions of a second to several million or billion years.
Radioactive Decay Calculator ... Radioactive Decay: ... * - Only the first 9 isotope have UBC disposal limits. Refer to your licence or contact your radiation safety office for the disposal limits of other isotopes. ** - Field at surface of container must also be < 0.25 mR/h (2.5 uSv/h). ...
Half-Life Calculator. Use this decay calculator to easily calculate the time elapsed since the beginning of the decay, or calculate the original quantity, half-life or remaining quantity of a substance subject to radioactive decay, based on any of the three parameters.
This phenomenon was termed as Radioactive Decay. The element or isotope which emits radiation and undergoes the process of radioactivity is called Radioactive Element. Radioactive decay occurs when the original nucleus or the parent nucleus of an unstable atom decomposes and forms a different nucleus or the daughter nucleus.
An element's radioactive decay can be determined through a single equation which requires imputing the isotope's half life, its rate of decay and the decay time since the rate of decay is measured. Every isotope has its own half-life. The half-life is the amount of time it takes for a given quantity of the isotope to lose half of its radioactivity.
