The total mass of the isotope is indicated by the numerical superscript.
While the lighter isotopes C has decayed that what remains can no longer be measured. In 5,730 years half of the C in the atmosphere, and therefore in plants and animals, has not always been constant.
But without reliable witnesses the accuracy of the watch makes no difference.
You can only establish the time for the race if it was timed by two or more qualified eyewitnesses who observed the start, the progress and the finish.
This is affected by solar activity and the earth’s magnetic field.But they do not even mention the basic problem that you cannot know the radioactive concentrations that existed in the rock in the past.In other words, the fatal problem with all radioactive dates is that they are all based on assumptions about the past.That is why you need at least two, sometimes three judges to measure the time of the race to the standard needed to enter the record books.
It would make no difference how accurate or high-tech the wristwatch was.From these records a “calibration curve” can be built (see figure 2, below).A huge amount of work is currently underway to extend and improve the calibration curve.Professor Willard Libby produced the first radiocarbon dates in 1949 and was later awarded the Nobel Prize for his efforts.
