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 ...

This is the equation used in our half-life calculator as well. Half-Life formula. You can find the half-life of a radioactive element using the formula: where t 1/2 is the half-life of the particle, t is the elapsed time, N 0 is the quantity in the beginning, and N t is the quantity at time t. Exponential decay applications

The radioactive materials contain unstable nuclei and undergo radioactive decay. The nuclear decay formula is calculated by multiplying 1000 with initial number of moles, exponent value of element and time period is divided by 1000. The nuclear decay equation is an efficient way to find the number of moles remaining in the nuclei.

Decay Law – Equation – Formula. 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”. This constant probability may vary greatly between different types of nuclei, leading to the many different observed decay rates.
