For example, the radioactive isotope potassium decays to argon with a half life of 1. In the case of rapid growth, we may choose the exponential growth function: .. The formula for radioactive decay is important in radiocarbon dating, which is. Earth sciences portal Geophysics portal Physics portal.

The half-life of plutonium is 80, years. Carbon dating is based upon the decay of 14C, a radioactive isotope of At this point, the overall amount of 14C in the organism begins to decay exponentially. For most radioactive nuclides, the half-life depends solely on nuclear properties and is essentially a constant.

He is interested in various theoretical aspects of radiation and radiological physics, with an interest in mathematical modelling in general. The exponential decay formula is given by: m(t)=m0e−rt. where r=ln2h, h = half- life of Carbon = years, m0 is of the initial mass of the. This converts the only stable isotope of iodine I into Xe via neutron capture followed by beta decay of I.

This transformation may be accomplished in a number of different ways, including alpha decay emission of alpha particles and beta decay electron emission, positron emission, or electron capture. Exactly the same treatment can be applied to radioactive decay. . Recall that the exponential law for the number of Carbon 14 nuclei present. Note that that the domain of F is the interval from zero to 1, which corresponds to the interval of time from zero to infinity.
