The diffusion values that were measured (the amount of gas that came out of the rock in a certain period of time at certain temperatures) were used as equivalent values to the natural environment (Henke, 2005).
Another serious procedural error is that there is no distinction in the amount of Helium diffused that separates Helium would be the result of decay, so to simply state that a certain amount of Helium diffused from the rock would be inaccurately representing the facts.

Scientists usually look at the daughter product of the decay in order to determine the approximate age of a rock or mineral.
The reasoning for this is that the helium release by alpha decay can too easily escape the surrounding rock. Over a long period of time, the parent element will decay at a calculable rate into the daughter product.
With more of the parent product existing in the rock sample, more of the daughter product will have been created; with less of the parent product existing in the rock sample, less of the daughter product will have developed.
The resulting plotted points should line up near a single sloping line which is then used to calculate the age.
They have a son named Sam who was born in July 1999. There trucks were a dark brown sort of like the present day UPS. Radiocarbon dating measures the amount of carbon-14 left in human or plant remains, and then scientists can estimate the amount of time the thing has been dead LSD which seems to have ruined his life along with marijuana hashiish and Methamphetamine and Seconal, he was a walking talking pharmacy till after his ingestion of 125 micrograms of LSD 25 where he became a PLANT!
