WebIn the first place, since the unknown term in radiometric dating is obviously t, it is desirable to rearrange equation 4 so that it is explicitly solved for t. Second, the more common way to express the intrinsic decay rate of a radioisotope is through its half-life (abbreviated t 1/2 ) rather than through the decay constant λ. WebNot carbon-14 dating. It only works for living organisms on Earth where we know the historical atmospheric production rate and the exchange of carbon cuts off at their death. Also, it is restricted to only around 50,000 years max. So, it is pretty much useless in geological dating. We can use other radiometric dating techniques though.
