Organic material carbon dating
Scientists have developed calibration techniques to adjust for these fluctuations.
While alive, all plants and animals take C14 into their bodies.
We focused our collection efforts on tiny pieces of these materials, along with reed and straw left by the ancient builders.
In 1984 we conducted radiocarbon dating on material from Egyptian Old Kingdom monuments (financed by friends and supporters of the Edgar Cayce Foundation).
As soon as a plant or animal dies, the carbon uptake stops.
The radioactive carbon isotope is no longer replenished; it only decays.
Scientists have calculated the rate at which C14 decays.
Test results from Middle Kingdom pyramid (Senwosret II).
Ancient Egypt’s population was restricted to the narrow confines of the Nile Valley with, we assume, a sparse cover of trees.

In spite of this discrepancy, the radiocarbon dates confirmed that the Great Pyramid belonged to the historical era studied by Egyptologists. Koch Foundation supported us for another round of radiocarbon dating.
