Note that the mere existence of these assumptions do not render the simpler dating methods entirely useless.In many cases, there are independent cues (such as geologic setting or the chemistry of the specimen) which can suggest that such assumptions are entirely reasonable.
But before your visions of grandeur run rampant and your checkbook becomes more hollow than Landis’ Maillot Jaune, are you sure carbon is the right frame material for your needs?
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.

Is it still relevant now with advances in carbon and carbon repair? By Kurt Gensheimer So you’re about to mosey on over to your local bike shop and drop more coin for your first genuine racing bike than most people pay for an entire motorcycle.
The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth.
