Decay Time of Radioactive Isotope Calculator
t1/2 = Half-life of the isotope; T = Time taken for the specific decay ; Wini = Initial amount of the radioactive isotope; Wfin = Final amount of the radioactive isotope
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.
