The water level just sits there even though the hose is going full blast.(The barrel is made deep enough so that we don't have to worry about water overflowing the rim.) Henry Morris argued that if we started filling up our empty barrel it would take 30,000 years to reach the equilibrium point.When an organism dies (whether plant or animal) its intake of carbon atoms ceases.The starting ratio of radiocarbon to stable carbon is locked in at that point. The purpose in each of these methods is to determine the ratio of radiocarbon to stable carbon in the sample.Finally, when the water reaches a certain level in the barrel, the amount of water going into the barrel is equal to the amount leaking out the perforated sides.We say that the input and output of water is in equilibrium.The following article is primarily based on a discussion of radiocarbon dating found in The Biblical Chronologist Volume 5, Number 1. Radiocarbon dating is based on a few relatively simple principles. The vast majority of these are C (pronounced "c twelve"), the stable isotope of carbon.
It provides an objective, absolute method of determining a sample's age with quantifiable precision.The raw radiocarbon date of any sample can then be converted to true date by using this calibration table.This calibration step eliminates any concern about fluctuations in historic radiocarbon to stable carbon ratios or decay rates.The water leaking out the sides of the barrel represents the loss (mainly by radioactive decay) of the atmosphere's supply of carbon-14.
