Although a member of the carbon family, lead looks and behaves very differently from carbon.

Lead is one of only a few elements known to ancient peoples.

Over time the uranium-238 very slowly decays into uranium-234 (half-life = 248,000 ).

Radium-226 in the soil exhibits the same level of radioactivity as uranium-238 from which it was originally derived, because of a natural phenomenon called secular equilibrium.

The equation is the one which describes radioactive decay: If one of these assumptions has been violated, the simple computation above yields an incorrect age.Isochron methods avoid the problems which can potentially result from both of the above assumptions.Isochron dating requires a fourth measurement to be taken, which is the amount of a different isotope of the same element as the daughter product of radioactive decay.
