Range of carbon dating
This happens whenever there is a wiggle in the curve at the time the samples died.This, in fact, is the most significant factor contributing to loss of precision in radiocarbon dates today.There are two main factors which determine the precision of a radiocarbon date.Modern accelerator mass spectrometry (used for radiocarbon dating purposes to separate radiocarbon atoms from stable carbon atoms and count them) is quite precise.
Thus it is possible in some instances for two samples from a few decades apart to have the same radiocarbon concentration today, and hence the same apparent radiocarbon age..pass_color_to_child_links a.u-inline.u-margin-left--xs.u-margin-right--sm.u-padding-left--xs.u-padding-right--xs.u-absolute.u-absolute--center.u-width--100.u-flex-align-self--center.u-flex-justify--between.u-serif-font-main--regular.js-wf-loaded .u-serif-font-main--regular.amp-page .u-serif-font-main--regular.u-border-radius--ellipse.u-hover-bg--black-transparent.web_page .u-hover-bg--black-transparent:hover.

However, this contribution is usually only a few decades.Radiocarbon dates are certainly not precise to within a year or two, but they are generally precise to within a few hundred years or better.
