Measurements can be made with a high degree of precision. Aardsma submitted a sample from a reed mat known to be over 5,000 years old.The measurement, before calibration, came back with an error bar of /- about 60 radiocarbon years. It should be noted that these measurement uncertainties do not increase linearly as one goes back in time.Modern radiocarbon dating uses tree-ring chronologies to produce the calibration curve.

Radiocarbon Every day cosmic rays bombard our atmosphere.
These cosmic rays release free neutrons which zip around our nitrogen rich atmosphere at high velocities.
Here I will present what radiocarbon is, the dating methods, the assumptions that govern them, and the known discrepancies that plague the method.
With a thorough understanding of this dating method, it is my opinion that its ingenious fundamentals can be appreciated, yet greatly overshadowed by its limitations.
Since a small fraction of CO2 contains C14, some of carbon fixed within the plant is that of C14.
Animals eat the plants, ingesting the C14 which in turn enters the animal’s tissues (Warf, 212).For example, modern biblical chronology dates Noah's Flood to 3520 /- 21 B.
